Well, but the video is wrong. You can't use 1/2 mv^2 in special relativity, because it doesn't hold in special relativity... And the doppler effect in the case of the video is not uniform, the frequency and therefore the energy of the light would depend on the direction it's travelling in.

Title: "Energy, Mass, and Light: An Exploration of Fundamental Concepts" Abstract: This paper explores fundamental concepts related to energy, mass, and the nature of light. It delves into the famous equation E=mc^2 and its implications, discussing the energy-mass equivalence principle. Additionally, it examines the concept of light as both wave and particle, discussing its energy, frequency, and speed. The paper also addresses the idea of photons having mass and explores the relationship between energy, frequency, and mass in the context of light. Introduction: The concept of energy-mass equivalence, as encapsulated by Einstein's equation E=mc^2, is a fundamental principle in modern physics. It states that energy (E) and mass (m) are interchangeable, with the speed of light (c) acting as the conversion factor. This equation has profound implications for our understanding of the universe. Section 1: E=mc^2 E=mc^2 explains the relationship between energy, mass, and the speed of light. Mass can be converted into energy and vice versa. Practical applications and implications include nuclear energy and the mass-defect in chemical reactions. Section 2: The Nature of Light Light exhibits both wave-like and particle-like behaviors. As a wave, light is characterized by its frequency (f) and wavelength (λ). As a particle, light is composed of photons, carrying energy and exhibiting mass-energy equivalence. Section 3: Photons and Mass Photons are associated with a tiny amount of mass due to their energy content. Calculations for the mass of photons yield extremely small values. Section 4: Energy, Frequency, and Mass The relationship between energy, frequency, and mass in the context of light is explored. The equation E=hf (where h is Planck's constant) is discussed in relation to E=mc^2. Key Values and Concepts: Speed of light (c) = 299,792,458 meters per second. Planck's constant (h) = 6.62607015 x 10^-34 Joule seconds (approximately). List of Colors and Corresponding Frequencies: Red Light: Wavelength Range: 620 nm to 750 nm, Frequency Range: 400 THz to 483 THz Orange Light: Wavelength Range: 590 nm to 620 nm, Frequency Range: 483 THz to 508 THz Yellow Light: Wavelength Range: 570 nm to 590 nm, Frequency Range: 508 THz to 526 THz Green Light: Wavelength Range: 495 nm to 570 nm, Frequency Range: 526 THz to 606 THz Blue Light: Wavelength Range: 450 nm to 495 nm, Frequency Range: 606 THz to 668 THz Violet Light: Wavelength Range: 380 nm to 450 nm, Frequency Range: 668 THz to 789 THz Mass of Photons for Each Color (based on energy content): Red Light: Approximately 5.5217 x 10^-36 kilograms Orange Light: Approximately 4.4897 x 10^-36 kilograms Yellow Light: Approximately 3.6565 x 10^-36 kilograms Green Light: Approximately 2.6649 x 10^-36 kilograms Blue Light: Approximately 1.6783 x 10^-36 kilograms Violet Light: Approximately 9.2951 x 10^-37 kilograms Conversion Calculations: Conversion of energy to mass: Using E=mc^2, mass (m) can be calculated by dividing energy (E) by the speed of light squared (c^2). Conversion of mass to energy: Using E=mc^2, energy (E) can be calculated by multiplying mass (m) by the speed of light squared (c^2). Conclusion: This paper has provided an overview of fundamental concepts related to energy, mass, and light, emphasizing the interconnectedness of these concepts. It highlights the significance of E=mc^2 in understanding the conversion of mass into energy and the role of photons in carrying both energy and a minute amount of mass. Further research and exploration in these areas continue to deepen our understanding of the physical world. Please note that this summary includes numerical values and lists of colors, frequencies, and corresponding masses, providing a quantitative aspect to the paper's content.

1:30 Is it an assumption that the total energy change of the cat is the same in both scenarios? If not, then why? After all, in the first scenario the total energy change from both emitted radiation and kinetic energy is entirely measured in a frame moving with velocity v relative to cat while in the second scenario, the total energy change is measured using TWO frames , one frame at rest when measuring emitted energy from cat and then the kinetic energy is measured in a frame moving at constant velocity v relative to cat.

[@aleeex2683]

Let me explain this in a better way. instead of saying that i saw the cat emit photons and then got into the spaceship, lets say that there are two observers( me and my bro). lets say me and the cat are both at rest while my bro is travelling at a spaceship. After i see the cat emit photons i get into my bro's spaceship. on the other hand my bro had been on the spaceship from the very beginning. so when he saw the cat emit photons, the cat was still moving with respect to him. right now me and my bro are both in the spaceship meaning our frame of reference are the same. so we must see the cat having the same amount of energy. thats why the 1st equation that described the cat's energy from my pov for the entire experiment must be equal to the 2nd equation that described the cat's energy from my bro's pov for the entire experiment. if you want to understand anything else about this video feel free to ask

[@sagarshrestha5800]

Photon has speed limit if it is alone but in huge amount it can increase its speed. To remember. 1. For something to oppose something, they should exhibit or made up of same basic materials. For eg. Only the positive mass can repel positive mass. Or imagine 🧲 magnet with two similar pole. Let's imagine a scenario , A) Ball(having mass 'm') has speed limit because of air.(terminal velocity) Here both air and ball has same properties i.e. mass and occupy same space. Scenario 1. Ball falls down on earth with initial velocity=0. at some velocity it reaches terminal velocity called " C " because of opposing force which later equals to the force exerted by ball (mass 'm') Scenario 2. Ball is thrown by a person vertically downward . At first, the ball(m) velocity will increase greater than terminal velocity 'C' but afterwards it will come back to the speed of terminal velocity 'C' since the air limited to that area needs more time to oppose that additional energy in ball than in scenario 1. B) Let's increase the mass of the ball (i.e increase the number of atoms in the ball) I.e. (m+1) Scenario 3. the ball (m+1) will fall down with initial velocity '0'. But here since the mass of the ball is increased but the amount of air remains the same, the ball will have increased terminal velocity 'N' N > C 1.This means that for the light to have constant velocity, there must be some small particle (smaller than light) having same properties as that of light in the so called vacuum. 2. We can increase the velocity of light similarly by adding the similar properties properties that made the light.

It is just a viewer observation which is a part of Relativity. 0:44 Cat has energy since from your point of view it is moving and hence has kinetic energy. The kinetic energy converts into light energy meaning Energy of cat= KE-E 1:08 Doppler effect which is relativistic light energy 1:12 Recap of every scenario we have created yet. 1:31 Law of conservation of energy 1:49 Simplification 1:57 E=Mc²

You should put a disclaimer that this is more of a illustration of the concept, rather than a real proof. Both the equations of the kinetic energy and doppler effect are not the correct equations. You only used your equation for the doppler effect such that it has the desired outcome, rather than that it is physically correct.

[@zoltankurti]

Finally somebody who noticed...

[@jpaxonreyes]

That makes sense. I tried to redo the calculation with the relativistic kinetic energy instead of the classical, but kept everything else the same, and found that it didn't work. I just assumed that the Doppler shift in the video was correct. Now that you say it's not, I'm guessing there was a gamma in the Doppler shift factor that Minute Physics Taylor-expanded for small v (because I recognize the 1 + e²/2 signature of the expansion of gamma to second-order of e). Then with that gamma expanded for small v, he had to use the expanded (i.e., classical) kinetic energy. Is that what happened?

[@gokulanvethanayakam564]

Following on, at 1:49, Ev^2/2c^2 + 0.5*m2*v^2 = 0.5*m1*v^2 Ev^2/2c^2 = 0.5*m1*v^2 - 0.5*m2*v^2 Ev^2/2c^2 = 0.5*(m1-m2)*v^2 Now the LH v^2 and the 2 can be cancelled out with the RH v^2 and 0.5 respectively.

[@AdamRTNewman]

Why is KE=(1/2)mv^2 being used in a relativistic setting, when it's a completely non-relativistic formula?

[@TheColdBloodedGamerS]

Adam Newman Same thing happens when you try to actually calculate the energy levels of an atom. Ex : E =1/2mv^2-e^2/r :)

[@AdamRTNewman]

But isn't what you've just said there based on the non-relativistic Bohr model? As I understand it, the first approximately accurate model of the hydrogen atom was the non-relativistic Schrodinger model, which came later than the Bohr model. The Bohr model was completely wrong in its neo-Newtonian description of electron orbits, and completely wrong in its quantisation of angular momentum. Yet almost by coincidence, its prediction of energy levels coincides with that of the Schrodinger model, which is approximately accurate. However, even the Schrodinger model isn't 100% accurate, and one of the ways to improve on it is to replace Schrodinger's non-relativistic quantum theory with Dirac's relativistic quantum theory.

[@TheColdBloodedGamerS]

Adam Newman Yes Bohr model was something like a "cure". It was intended to explain why we can't use classical methods for the atoms (the one with the quantum states as orbits around the nucleus ). I also agree with the approximation of 100% percent. (sorry if my English is bad)

[@zoltankurti]

@@vedantsridhar8378 here, I can do one better. Anybody who said they understood the video successfully decived themselves. That is because this video has multiple mistakes in it which cancel out.
