Classical mechanics - two main concepts worth knowing. The first is Newton’s second law: F= ma: Force equals mass times acceleration. If you apply a force to a fixed mass, it tells you how much acceleration you will get. And knowing acceleration which is the change in velocity, you can make predictions. The second equation is the law of universal gravitation. it allows us to determine the motion of heavenly bodies. It says that the gravitational attraction between two bodies is the product of their masses divided by the distance between them squared, times a constant, called Newton’s gravitational constant. Energy is not a vector like force or momentum, but it is just a number. Work is closely related to energy. It is force times distance traveled. Energy for most objects consists of kinetic energy plus potential energy. KE is the energy of motion, It is KE = ½ M V^2 – the more mass you have and/or the more velocity you have, the more energy you have. Gravitational potential energy is expressed as PE = m g h – mass times the gravitational acceleration times the height. The total energy of an object is both Kinetic energy plus potential energy. Potential energy can take many forms. Gasoline or petrol has chemical potential energy. Important: Energy is always conserved. It is not created or destroyed. It only changes form. Thermodynamics is the study of work, heat, and energy on a system. We showed energy is how much work you could do. But another form of energy is thermal energy. If a car is moving and you apply the brakes, the kinetic energy of the car gets converted to thermal energy, created by friction of the car’s brakes. Temperature is the average kinetic energy of atoms in a system. Thermal energy is the total kinetic energy of atoms in a system. Entropy is a measure of disorder, or more accurately, the information required to describe the micro states of a system. The 2nd law of thermodynamics states that entropy of an isolated system can never decrease. Energy at lower entropy can do more work than energy at high entropy. The one way flow of Entropy seems to be the only reason we have a forward flow of time. Electromagnetism is the study of the interaction between electrically charged particles. The essentials are in Maxwell’s equations. If you have a static object with a charge, it will affect only other charges. If you have a static magnet, it will affect only other magnets. It will not affect charges. But if you have a moving charge, it will affect a magnet. And if you have a moving magnet, it will affect a charge. The constants mu naught and epsilon naught are the permeability and permittivity of free space. These two constants determine the speed of light because they measure the resistance of space to changing electric and magnetic fields. Special Relativity: Einstein presumed that the speed is the same in any frame of reference. This was one of the postulates. The second postulate was principle of relativity - the laws of physics are the same for all observes who are moving at the same velocity relative to each other. Einstein showed that the only way these can be true is if time was not fixed, but was relative. General relativity: Later Einstein showed using the same assumptions, there would be no way to tell if you were in an accelerating reference frame or standing stationary on earth. A flashlight beam will bend in gravity. But since light always takes the shortest path between any two points, this means that space-time itself is bending. Quantum mechanics: Three principles are important. First by Max Planck, says that energy is not continuous, but is quantized. The amount of energy equals the frequency of the radiation times Planck's constant. Using this, Einstein later showed that a photon is both a wave and a particle. The second is the Heisenberg's uncertainty principle: you cannot know both a particle’s exact position and it’s exact momentum at the same time. For a particle with mass, this means if you know exactly where a particle is, you don’t know how fast going. If you know exactly how fast it’s going, you don’t know where it is. #allphysics #arvinash Schrodinger's equation: prior to measurement, quantum systems are in superposed states. This means that their properties can only be expressed as a wave function. A wave function simplified, is a set of probabilities. So in a hydrogen atom, you can’t know where to find the electron in advance. All you can know is the probability of where you might find it, if you measured it. Prior to measurement, all quantum systems are waves of probabilities. This is not a limitation of our measuring devices. It is a limitation of reality. Become a patron: 🤍

Neil deGrasse Tyson Explains The Weirdness of Quantum Physics

Quantum mechanics is the area of physics that deals with the behaviour of atoms and particles on microscopic scales. Since its inception, the many counter-intuitive aspects and results of quantum mechanics have provoked strong philosophical debates and many interpretations. Neil deGrasse Tyson explains quantum physics in a way that is understandable even for the lay person. In Quantum Mechanics there is no such thing as absolute certainty when looking for something. This phenomenon is known as Uncertainty Principle and was Introduced first in 1927 by the German physicist Werner Heisenberg. Heisenberg realized that one implication of quantum physics is that the act of measurement always disturbs the object measured. Neil deGrasse Tyson explains that the whole computer world is based on the principle of Quantum Physics. We are able to manipulate the electrical properties of silicon only because we can study the wave nature of electrons. Our daily routines are often governed by technology that is directly related to Quantum Physics, thus our lives rest upon these fundamental scientific discoveries. Another hard concept to grasp is Quantum entanglement. Einstein referred to it as "spooky action at a distance. It occurs when a pair or group of particles is generated, interact, or share spatial proximity in a way such that the quantum state of each particle of the pair or group cannot be described independently of the state of the others. But Neil deGrasse Tyson and Lawrence Krauss explain this concept with everyday life examples which makes it a little bit easier to understand. As Neil deGrasse Tyson points out, the first quantum phenomena were observed more than a century ago. However scientists are still learning about this realm of our universe. #neiltyson #quantumphysics #science SUBSCRIBE to our channel "Science Time": 🤍 SUPPORT us on Patreon: 🤍 BUY Science Time Merch: 🤍 Sources: House Science & National Labs Caucus: Neil deGrasse Tyson 🤍 Accessed 01.03.2021 Lawrence Krauss - Connoway Hall - 🤍 Accessed 12.03.2021 In the Blink of Bird’s Eye, a Model for Quantum Navigation 🤍 retrieved 10.03.2021 Satellite-to-ground quantum-limited communication using a 50-kg-class microsatellite 🤍 Accessed 11.03.2021 NASA's Cold Atom Lab Takes One Giant Leap for Quantum Science 🤍 Accessed 09.03.2021 NASA’s Cold Atom Lab: The Coolest Experiment in the Universe 🤍 Accessed 02.03.2021 Why do quantum effects only happen on the atomic scale? 🤍 retrieved 01.03.2021 Neil deGrasse Tyson JRE #919 🤍 retrieved 26.02.2017

Everything we know about physics - and a few things we don't - in a simple map. #physics #DomainOfScience If you are interested in buying a print you can buy it as a poster here: North America: 🤍 Everywhere else: 🤍 French version: 🤍 Spanish Version: 🤍 Or on a load of other objects: 🤍 Also you can download a digital version here: 🤍 I made the music, which you can find on my Soundcloud if you'd like to get lost in some cosmic jam. 🤍 Errata and clarifications. I endeavour to be as accurate as possible in my videos, but I am human and definitely don’t know everything, so there are sometimes mistakes. Also, due to the nature of my videos, there are bound to be oversimplifications. Some of these are intentional because I don’t have time to go into full detail, but sometimes they are unintentional and here is where I clear them up. 1. “Isaac Newton invented calculus.” Actually there is controversy over who invented calculus first Isaac Newton or Gottfried Leibniz. Regardless of who it was I have used Leibniz’s mathematical notation here and so he definitely deserves credit. I did’t know about all this so thanks to those who pointed it out. 🤍 2. “Maxwell derived the laws of electromagnetism.” This is a simplification as Maxwell’s work was built on the backs of other scientists like Hans Christian Ørsted, André-Marie Ampère and Michael Faraday who discovered induction and saw that electricity and magnetism were part of the same thing. But it was Maxwell who worked out all the maths and brought electricity and magnetism together into a unified theory. 🤍 3. “Entropy is a measure of order and disorder”. This is also a simplification and this does a good job of explaining it better 🤍 4. Einstein and Quantum physics: I made it sound like quantum physics was built by people other than Einstein, but this couldn’t be further from the truth. Einstein got a Nobel prize for his work on the photoelectric effect which was a key result to show the particle-like nature of light. Funnily enough he never got a nobel prize for his work on Relativity!

According to research on galaxies and other large-scale formations, there are many mysteries in the cosmos that are just being discovered by scientists. . Most of these mysteries require new physics theories to help us understand them. For example, we need to understand why gravity is so much weaker than the other forces, as well as what happened before and during the big bang and many other unanswered phenomena. We've been able to address some of our questions thanks to the advancements in technology. And CERN has consistently been at the forefront of this. Incredibly, the CERN team of scientists has just uncovered a breakthrough discovery that alters the course of history! What did they find, and how might it answer our questions about the cosmos?

Our understanding of the universe has already been overturned several times. Let us recall in passing of the astronomical world view which our ancestors possessed, where Earth embodied the center of the cosmos, circled by all remaining objects. In the meantime, however, we know that our blue home planet is no more than a tiny piece of the mosaic in an overwhelming construct that we still haven't deciphered. It is thanks to experts like Edwin Hubble that we understand our galactic home more precisely than ever before. The American achieved several milestones in the course of his life: He classified the spiral galaxies, researched the expansion of the cosmos and, last but not least, came across the Hubble constant. But why is this fundamental parameter of cosmology so important? What answers can this parameter give us? And finally: Why do the latest observations of the Hubble Space Telescope suggest that something is wrong with our understanding of the universe?

Professor Jim Al-Khalili traces the story of arguably the most important, accurate and yet perplexing scientific theory ever: quantum physics. The story of quantum physics starts at the beginning of the 20th century with scientists trying to better understand how light bulbs work. This simple question soon led scientists deep into the hidden workings of matter, into the sub-atomic building blocks of the world around us. Here they discovered phenomena unlike any encountered before - a realm where things can be in many places at once, where chance and probability call the shots and where reality appears to only truly exist when we observe it. Albert Einstein hated the idea that nature, at its most fundamental level, is governed by chance. Jim reveals how in the 1930's, Einstein thought he'd found a fatal flaw in quantum physics. This was not taken seriously until it was tested in the 1960s. Professor Al-Khalili repeats this critical experiment, posing the question does reality really exist, or do we conjure it into existence by the act of observation? Elsewhere, we explore how the most famous law of quantum physics – The Uncertainty Principle – is obeyed by plants and trees as they capture sunlight during the vital process of photosynthesis. Could quantum mechanics explain the greatest mystery in biology - evolution? Content Provided By TVF International.

Are atoms real? Of course they are. Everybody believes in atoms, even people who don’t believe in evolution or climate change. If we didn’t have atoms, how could we have atomic bombs? But you can’t see an atom directly. And even though atoms were first conceived and named by ancient Greeks, it was not until the last century that they achieved the status of actual physical entities — real as apples, real as the moon. #science #documentary #theuniverse #space

Purchasing items from the links on these pages will help support my IG page of science and wonder. Buy physicsfun toys on : 🤍 (Official websit 🇺🇸) physicsfun toys on amazon : 🤍 Follow on Instagram : 🤍physicsfun This video contains : 👉🏻 Ambiguous Object Illusion: repost of this incredible design by Kokichi Sugihara of Meiji University in Japan, the inventor of this illusion and art form. 👉🏻 Perpetual Motion Simulator: this marble machine device does not break any laws of thermodynamics- but it sure looks like it! When I first saw videos of this piece of kinetic art I thought the effect was due to video editing, but in fact the base contains a power source and very clever mechanism (I used compass for clue/partial reveal). An amazing piece of art by William Le crafted from stainless steel wire, doussie hardwood, and undisclosed internal components. A remarkable addition to my collection!  👉🏻 Monochromatic Room 🤍exploratorium: a photo of colorful San Francisco is illuminated by a very narrow frequency band of light, with a wavelength of 589nm- the characteristic spectrum of sodium vapor lamps at low pressure. 👉🏻 Copycoder: clever use of an array of cylindrical lenses to scramble and unscramble large font messages- a modern "secret code" toy. 👉🏻 Vortex Marble: glass art intersects with the physics of optics in this lampwork art form invented by Kevin O’Grady circa 1994- and this marble bears his signature mark on the back. 👉🏻 Scale Solar System 👉🏻 Scale Solar System Sticker Set: one of the most amazing facts about the planets in our solar system is their relative sizes. Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, Neptune, and dwarf planet Pluto included for comparison- all in their current order (sometimes Pluto is closer than Neptune), and mounted here on a sheet of polycarbonate. On this scale, Neptune would be about 5 kilometers away from Mercury!  👉🏻 Moondrop: using magnets and Lenz's Law to imitate free fall times on the Moon and Mars. 👉🏻 Plasma Arc Lighter Physics: dual arcs of plasma exceed 1100 C (2000 F) on this flameless lighter. 👉🏻 Halloween Neon Glow Bulb: the pumpkins, with a high voltage between them, glow orange with light from the emission spectrum of the excited neon atoms of the low pressure gas within the bulb. 👉🏻 Uranium Metal: at Z=92 protons, uranium is the largest naturally occurring atom one can extract from the Earth. 👉🏻 Oil Drop Timer: immiscible liquids (colored oil in kerosine) in two connected containers.

Hi Everyone :) Welcome back! I get asked often: "Where did you get all this stuff?" My goal is to share the real magic of science and physics- and to this end I will update here (and in my store) suggestions on where to get some of these toys, kinetic art pieces, and scientific curiosities for yourself. Purchasing items from the links on these pages will help support my IG page of science and wonder. Buy physicsfun toys on : 🤍 (Official websit 🇺🇸) physicsfun toys on amazon : 🤍 Follow on Instagram : 🤍physicsfun This video contains : 👉🏻 Single Tube Nixie Clock: This minimalist clock uses a standard 5V USB connection and modern electronics to power a single Russian made ИH-14A Nixie tube- here the display shows the time 12:36 flashed in sequence. 👉🏻 CMYK Coasters: physics and psychophysics of four color printing demonstrated with acrylic slides that assemble to reveal Vermeer's "Girl with a Pearl Earring". Cyan, magenta, yellow, and black (key) comprise the elements of the subtractive color model used in most color printing. 👉🏻 Physics toys featured in famous movies and series 1) Drinking Bird Heat Engine: time lapse of 15 minutes into 15 seconds (4 cycles). Cooling by evaporation at the head leads to lower pressure in the top bulb, the dichloromethane fluid rises up the neck making the bird top heavy and the bird tips over dipping its beak and letting the fluid return to the bottom bulb. The time lapse allows a clearer picture of how the fluid rises, shifting the center of mass, and how tipping makes the glass column lift out of the fluid in the bottom allowing the pressure to equalize and letting gravity pull the fluid to return to the base. Process repeats as long as the top stays wet. So much physics in one hypnotic toy! 2) Van de Graaff Generator: this miniature electrostatic generator can create potentials of more than 50,000 volts allowing sparks to jump a few centimeters through dry air. Similar physics to the sparks created when shoes scuff on carpet, a moving rubber dielectric belt carries electrons away from the top sphere leaving it positive charged- as can be seen by the electrostatic repulsion of some Mylar strands. A small battery powered 3V motor drives the belt via the bottom pulley in this unit that costs less than $10 US. 3) Switch Pitch Ball: this spherical assembly changes color by turning inside out when tossed into the air. Advertisements for this toy incorrectly claim air drag is involved in the transformation. The ball is made of multiple components hinged together. In launching the ball from the hand an upward acceleration results in a torque that pivots each component around its center of mass, causing the rotation of these components in an organized way leading to the transformation. Imagine tossing a stick straight up. If the stick is perfectly vertical upon launch it will move straight up- but if it is initially slanted at all it will also begin to rotate upon launch. Similar physics underlies the motion of each component of the ball- shown here in 240 fps slow motion. The Switch Pitch is produced by the makers of the Hoberman Sphere. 4) The Swinging Sticks: a driven coupled chaotic physical pendulum as kinetic art where the placement of the rods' axes of rotation are engineered to exhibit the widest range of interesting motion. Four AA batteries and a simple electromagnetic kicker circuit in the base gives a tiny push to a magnet in the end of the large rod, keeping the system in motion for over a year! Perhaps one of the most famous physics toys out there as it was featured in the movie Iron Man II (sitting on the desk of Pepper Potts). 👉🏻 Lenticular McFlys Prop 👉🏻 Confusing Physics Toys That Will Definitely Confuse You! 1) Trammel of Archimedes 2) 5-Shuttle Trammel of Archimedes 3) Hyperbola Hole 👉🏻 Twin Fan Lissajous: two rotating fans with LED lights form Lissajous figures when spun around common axis.

Hope this was worth the wait! So many people helped with this video: Prof John Sperry, Hank Green, Henry Reich, CGP Grey, Prof Poliakoff, my mum filmed for me in beautiful Stanley Park and Jen S helped with the fourth version of the script. Prof John Sperry 🤍 Hank Green (SciShow) 🤍 Henry Reich (minutephysics) 🤍 CGP Grey 🤍 Prof Poliakoff (Periodic Videos) 🤍 Also thanks to the Palais de la Decouverte - they helped me with the whole vacuum pump setup in Paris. No, I could not actually suck water up 10m - I did about 4m, but the vacuum pump was easily able to do it and I saw spontaneous boiling on all of our various trials. Footage from this may end up on 2Veritasium. Trees create immense negative pressures of 10's of atmospheres by evaporating water from nanoscale pores, sucking water up 100m in a state where it should be boiling but can't because the perfect xylem tubes contain no air bubbles, just so that most of it can evaporate in the process of absorbing a couple molecules of carbon dioxide. Now I didn't mention the cohesion of water (that it sticks to itself well) but this is implicit in the description of negative pressure, strong surface tension etc.

This physics video tutorial explains the concept behind Newton's First Law of motion as well as his second and third law of motion. This video contains plenty of examples and practice problems. This video is useful for high school and college students studying physics. My E-Book: 🤍 Video Playlists: 🤍 Homework Help: 🤍 Subscribe: 🤍 Support & Donations: 🤍 Youtube Membership: 🤍 Here is a list of topics on Newton's 3 Laws of Motion: 1. Newton's First Law of Motion - An object at rest will remain at rest unless acted on by an unbalanced force. 2. Second Part of Newton's First Law of Motion - An object in motion will continue in motion unless acted on by a net force 3. The net force is zero when an object moves with constant velocity 4. Newton's 1st Law of Motion Examples & Demonstrations - Ball rolling on a rough surface with friction such as a carpet vs a ball rolling on a smooth surface such as ice with very little kinetic friction. 5. Earth moves continually in space - lack of frictional forces 6. Newton's Second Law of Motion - Force = Mass times acceleration 7. Newton's 2nd Law of Motion - Force is proportional to mass and acceleration. Mass and acceleration are inversely related when the force applied is constant. 8. Newton's Third Law of Motion - Action Reaction Pairs. For every action force, there is an equal but opposite reaction force. 9. Newton's 3rd Law of Motion Examples - Astronaut throwing a ball in space. Fisherman throws a package out into see and experiences a recoil velocity. 10. Impulse equals force multiplied by time 11. Momentum - Mass in Motion. Momentum equals mass times velocity. 12. Scalar vs Vector Quantities - Magnitude and Direction 13. Impulse - Momentum Theorem 14. Variation of Newton's Second Law of Motion - Force is the rate of change of momentum 15. Applied Force, Frictional Force, Normal Force vs Weight Force 16. How to calculate Final Velocity / Speed Using Acceleration 17. Acceleration is the rate of change of velocity 18.

There's a lot more to physics than F = ma! In this physics mini lesson, I'll introduce you to the Lagrangian and Hamiltonian formulations of mechanics. Get the notes for free here: 🤍 When you take your first physics class, you learn all about F = ma-i.e. Isaac Newton's approach to classical mechanics. But there's a lot more to mechanics than F = ma, and modern physicists actually more commonly use two other formulations of mechanics: the Lagrangian and Hamiltonian formalisms. In this video, I'll teach you the basics of both. They're not only powerful approaches to classical mechanics, they're also fundamental to the way we think about quantum mechanics! Get the PROBLEM SHEET, the SOLUTIONS, and the ANIMATIONS: 🤍 More to learn: - All About Pendulums: 🤍 - The Principle of Least Action: 🤍 - The Relativistic Action: 🤍 - Noether's Theorem: 🤍 - Poisson Brackets: 🤍 Online tutoring inquiries: 🤍 If you find the content I’m creating valuable and would like to help make it possible for me to continue sharing more, please consider supporting me! You can make a recurring contribution at 🤍 or make a one time contribution at 🤍 Thank you so much! About physics mini lessons: In these intermediate-level physics lessons, I'll try to give you a self-contained introduction to some fascinating physics topics. If you're just getting started on your physics journey, you might not understand every single detail in every video-that's totally fine! What I'm really hoping is that you'll be inspired to go off and keep learning more on your own. About me: I’m Dr. Elliot Schneider. I love physics, and I want to help others learn (and learn to love) physics, too. Whether you’re a beginner just starting out with your physics studies, a more advanced student, or a lifelong learner, I hope you’ll find resources here that enable you to deepen your understanding of the laws of nature.
