Why gravity changes when you leave the Earth's surface
In short: This video explains how to calculate gravitational potential energy in scenarios where the gravitational field is no longer uniform, moving beyond simple approximations to handle large distances.
The video explores the transition from using a constant gravitational field to more complex calculations required at large distances. When objects move far enough away, the assumption of a uniform field fails, requiring a different mathematical approach to determine potential energy.
