How Acceleration Explains GRAVITY ? ( The Equivalence Principle)
HTML-код
- Опубликовано: 9 сен 2021
- This video is about how general relativity changes our view about who is accelerating. A stationary Observer in a gravitational field appears to be accelerating where its not accelerating. And a freely falling observer appears to be accelerating when its not. This happens because of geometry of spacetime. In general relativity space time is not flat but can get warped or curved. As a result of all this the very definition of inertial and non inertial reference frames gets changed. in this video we will deal with the Equivalence Principle to Understand how general relativity explains Gravity.

THANKS FOR WATCHING.
WRITTEN , HOSTED AND EDITED BY -
PRIYANSH NAMDEO.
see you in the next video.
Nicely done! Thanks for your contribution.
Love this. Thank you.
Well done sir!
💯👍Well said. Many people do not know this fact.
Its not a "fact". Its a foolish trick of rhetoric. The earth is NOT accelerating up, thus making us feel "gravity". The concept is insanity, totally irrational. Hard to believe that otherwise smart people accept such pseudoscience nonsense. Einstein is a fraud, not some genius.
A very good and clear explanation.
Thanks! glad you liked it.
Great job
Thanks
I remember a ninth-grade physics kid telling me that deceleration in physics is just 'acceleration' in another direction and that it's always considered 'acceleration'. but I think here that convention might confuse things.
While the equivalence principle holds true, and it 'feels' the same as acceleration in a rocket, it's a pretty important distinction to note that matter in a gravity well is experiencing deceleration as it tries to follow its straightest line through space time which has now taken a straight-line path through the center (core) of a gravity well.
It's actually even simpler than that. You don't even need to apply any pseudoscientific nonsense. Once an object is released from Earth's constant velocity upward vector, the object decelerates through resistance, only appearing like its accelerating in the downward vector.
Gravity is the result of space being both curved and also moving towards a mass.
Gravitational fields of forced motion holding mass together, is what vibrates the apple to the weakest point of resistance, in occupational space in equalization. Gravitational fields of forced motion, hold mass in equalization of flow in occupational space. Planets are Occupational space. Space is a stationary negative field of resistance. It repels planets equally from all sides. And inside as occupational. Proximity orbs like moons are in equalization of pressure except on the side of occupational space of the host planet. The momentum of spiraling force is in equalization of pressure between forces. Magnetic fields of force holding mass together in equalization are also a factor. Gravitational fields of force occupational space are in resistance as mass passes through space. Weakened resistance causes the occupational space to cause trajectories of passing smaller objects of mass, to curve towards the weakest occupational area of space. Resistance pushes mass towards Occupational space of least resistance. Gravitational fields of forced motion holding mass together are stronger forces, then Magnetic fields of force. Cycling motion in patterns throughout space as harmonics harmonization of frequencies flowing in direction motion of mass.

Why does an object thrown from different heights hit the ground at different speeds? If there is no acceleration in the geodesic
There is acceleration known as g.
Why gravity speed is accelerating?
why not velocity ?
The earth approaches-expanding- the released object at 16 feet per second per second constant acceleration: gravity. Taking the equivalence principle literally is the answer. “The Final Theory: Rethinking Our Scientific Legacy “, Mark McCutcheon for details. D=1/2 at^2 part of gravity equation.
We have never experienced in reality a 3d geometric object constantly accelerating in all directions without expansion. This is in the realm of pseudoscience, since man cannot investigate its origins, and we have no tangible evidence of it in reality. We know it not to be a force due to density and buoyancy ceasing to exist in freefall. We also know the Earth's reference frame of motion is a vector of constant upward velocity perpendicular to level by the simple fact that buoyancy always moves in the direction of motion. While still attached to the Earth's reference frame all buoyant materials rise straight up with the motion of the Earth. The geometric shape of Earth is now up for debate or we only live on one side of a sphere shooting straight down a worm hole.
@@sirturdaloter141 An accelerometer- slinky,water balloon or phone app- experiment Proves the earth is expanding at 16 feet per second per second constant acceleration: d=1/2at^2.
@@davidrandell2224 , no those experiments just prove that gravity is not a force and the direction of the reference frames vector. Expansion would be observed through warping of mass. We do not observe or experience that phenomenon.
@@davidrandell2224, it is not constant acceleration either. It is constant velocity. The appearance of acceleration comes through the deceleration of the object from the reference frame.
@@sirturdaloter141 So glad you have disproven Galileo! Remarkable. A 4 page gravity primer shows otherwise. themarginal. Dot com- being censored. See if you can find it/ disprove that also, physically.
I do not understand why do you mean by the earth accelerating? . I mean are you talking about the acceleration of the earth when it rotates or it spins around the sun? I mean ibdo not getvit if earth is moving upwards does it expanding 😭? I can not get it
No, he means that when you're falling, the earth is rushing upwards towards you. The surface of the earth is moving towards you and is accelerating towards you.
Interesting points. TY. Why is space curved near Earth?
Because mass or energy curves space time. And Earth is very massive. Everything with mass curves space-time. But bigger mass curves space-time more.
@@priyanshnamdeo Yeah but why does mass or energy curve spacetime?
@@alwaysdisputin9930 That's their property, like charge is a property that deflects magnetic field, similarly mass/energy is a property that bends spacetime
@@Saurav_100rav So you're saying energy (like charge) has a magic force field & it's impossible to explain why. Do you believe in magic?
If we both walk N, the space between us becomes smaller & smaller until we meet at the N Pole. Sure we could say "this is just a property of Earth" but it's better to say "gravity caused Earth to form a curved surface & parallel lines on a curved surface converge". But this raises the Q does mass fire little particles that causes space to become smaller? Or, inside each kg of mass is there a little BH that sucks in space?
@@alwaysdisputin9930
1. Force doesn't bends spacetime, mass and energy bends
2. There is lot of calculation behind how it bends. Over 10 complex equations called Einstein's field equations

You and everyone were "taught" this concept. Falling is absolute, accelerating, AND ALL OBSERVERS AGREE on exactly what is happening, which is GREATLY different than a velocity in space where each velocity has INFINITE definitions. This is EXACTLY like saying NO DEFINITION. That velocity means nothing to nature until it hits something. THEN, it becomes absolute. Stop practicing what you were taught, and try to make better sense of it, because following a crowd is always irresponsible.
Acceleration doesn't cause gravity. Since sun gravity accelerates us at 5900 m/s, we are thrown outward by centrifugal force due to earth orbital rotation, we are held in balance.
What I meant was that the effects of being in a gravitational field is similar to being in a state of acceleration.
And from the perspective of an inertial observer , it's acceleration that causes the effects that we generally attribute to the gravitational force.
@@priyanshnamdeo I don't think your title is bad and the video is definitely not bad (as in it's good 💙) but I think the confusion comes from the word "explain." You're using it as a metaphor to help explain gravity. I personally thought you meant that acceleration literally explains gravity. As in gravity is just the earth moving upwards like plenty of flat earth-ers do.
Acceleration is the change of velocity over time. The inertial frame allows you to ignore reality and facts. You are repeating nonsense you heard fr other people who forgot about thinking. Inertia used to means something real, not anymore. Kinetic energy isn't real anymore either, right? Not until your inertial frame hits the ground - reality. Time explains acceleration and mass has nothing to do with the acceleration, just the distortion of time. A binary process.
Mass modifies time, Time produces acceleration as in a=32 feet per second squared - TIME IS THE VARIABLE. Too easy to see.
Read a book. This is pathetic.
