Question

Describe Gravitational potential energy.

Answer 1

GRAVITATIONAL POTENTIAL ENERGY

➖➖➖➖➖➖➖➖➖➖➖➖➖➖

Work done in taking from infinite point to a point is knkwn as Gravitational potential energy.

$v \: = \: \frac{w}{m} \\ work \: w \: = \: m \: \times v \: \\ \\ poteential \: energy \: = \: m \times \: v$

Answer 2

I think there is a better way of looking it, but I cannot develop it all here.

My view is that the explicit energy in matter exists in two forms, and one is not really explicit at all. The remainder of the Energy is deemed to be so intrinsic and invariant that it really matters not anyway.

I believe Potential Energy is best thought of as Internal Kinetic Energy. As the strength of a Gravitational Field increases, then the External Energy of the two dimensional Photon is internalized whilst the Internal Kinetic Energy of three dimensional particles is externalized.

However, this comes with the Caveat that Energy is not invariant across gravitational reference frames, and so really little more than Mathematical Concept.
