(OLD VERSION) Gravitational potential energy explained

OLD VERSION
Please see for an updated, more robust version - • What is Gravitational ...
In this video, I briefly discuss gravitational potential energy (PE = mgh) as assumed knowledge and move not o understanding GPE in the larger scale, as gravity changes. I discuss how the formula comes about and what it look graphically.

Thank you for making this video! The concept now really makes sense and I really appreciate you making it so clear and easy to follow. Great explanation!!

[@jintumanibarman8459]

Very good to your comment I appreciate you

[@ferdousarachaity1220]

I'm currently an A-level student. It was taking me a while to grasp this new concept from my A-Level coursebook. But, this video has worked wonders for me leaving no more confusions. Thank you so much Professor!

[@nksingh6022]

Thank You So much sir☺ I have seen many education videos on gravitation but none has explained it as effectively and precisely as you. Despite of me being a non native English speaker , your english is like crystal clear and that's what's makes your youtube channel exceptional. May this channel reaches to new height in education field keep creating more educational videos. ☺

[@PhysicsHigh]

Thankyou for your kind words

How can you cancel the h with r as h is at certain height from earth surface while taking from center or either from surface h never equals to r

[@technoshrink]

This is an incorrect explanation on the part of the person in the video. height is not equal to r. The energy is just the definite integral of the force between the distance from the surface of the earth and the teddy bear. Force is just the instantaneous effect of gravity on the objects at a certain distance. If you add all those forces up at each infinitesimally small distance between the height of the teddy bear and the surface of the earth, you get the amount of energy. That's what the integral does. So, since the F = Gm1m2(r^-2), the integral with respect to r is -1/2Gm1m2(r^-1). Therefore substituting the r with the actual distance and multiplying by height, the distance between teddy and the surface will give you the sum of all instantaneous forces from 0 to 8m, in other words, the potential energy. No disrespect to the creator of the video. I actually like the content, just this particular thing was incorrect.

[@PhysicsHigh]

+Zane thanks for your feedback Zane.

[@lucifermorningstar8469]

Even if u cancel out the r... It will be inversely proportional to height.. n u still said GPE will increase with height

[@chjejwjs]

thank

[@shejuti04]

Is it me or does anyone notice howw cute that teddy is?

[@panghuatan6182]

yeah

[@azmatullah7860]

What; s difference between gravitational potential energy and absolute gravitational potential energy?

[@swapnilhogade3378]

good

[@cogniEFFICACY]

Could u pls tell me that why potential energy is considered negative of work done? ?

[@PhysicsHigh]

I thought the video explained this. Is there a part oft he video that is unclear?

[@dorenaretaga1939]

Deepakshi Bora it's because teddy cause down then obviously it's negative just take a look at a cartesian plane hehe

[@jimgerth6854]

So in this example can you calculate GPE final and initial with the Formular -Gmm/r and does the r stand for the distance from the earth?

[@pascal8534]

how do you calculate gpe if there is a ramp involved

[@ADNANKHAN-el2kw]

Plz make video on P.E and K.E also,G.P.E gravitational potential energy Plz

[@raghuseshadri7023]

DAve Is the height h the height of the lowest point on the object from the earth or the center of mass of the object from the earth? By extension, I am asking whether an object placed on the ground has any potential energy in it by virtue of its center of gravity always being at a certain height from the surface of earth.

[@robert2real]

This video is flawed from the start. Increase in potential energy is cause when Teddy is displaced from his position of equilibrium (inertia) through work. No need to invoke gravity as it is not a force but the curvature of spacetime according to the current rhetoric

[@PhysicsHigh]

Yes I know that gravity is not a force, as Newton saw it, but rather a curvature of spacetime. It’s pitched at high school, so the model I present is consistent with Newton but spacetime is a bit “heavy” for high school students.

[@Kudara]

You need to work on your g's mate

[@dubszzyt1132]

Can someone explain this without using equations😰

[@PotterheadDirectioner]

I don't understand. At the beginning you explained saying that you're edoing work but GPE is due to work done by the earth. In short I don't think this vid is correct

[@mmaxamazing4177]

nice arrows :>>

[@rinkisingh1694]

You are focusing on the arrows or the content

[@GoodNewsForStrangers]

4:45 Can someone please explain to me why the mass is gone and why he got rid of it?

[@PhysicsHigh]

m1 is on both sides of the equation so you can cancel on both sides

[@GoodNewsForStrangers]

Ah makes sense, thank you.

it didnt help me/ when i put teddy up there it feell done

[@remlover5294]

PrankTown17 that is the gravitational potential energy dummy😒😒😒

[@panghuatan6182]

teddy

[@paulvinet7667]

The one thing I don’t understand is this: if you can perform work through changes in the gravitational potential energy, it makes sense that whatever work/energy is gained is equal to however much it took to lift it in the first place. But what about things that just by happenstance in space ever close enough to our gravity well. I sort of understand how the energy isn’t going from large to small, but rather zero to large negative, but if that’s the case then where is this negative energy coming from? It seems like that would mean there’s this infinite source of potential usable energy in the universe between the earth and any random object which just happens to drift into our gravity well. No work was needed to move these objects into our gravity well, or at least the energy needed could be neglible since inertial forces can get something moving and it won’t ever stop. Like for example when andromeda plows into the Milky Way in however many billion years, there’s certain to be at least a few massive collisions (though less than one might think: there’s a lot of empty space in a galaxy), where does this new potential for USABLE work energy coming from? How is this not a free lunch?
