Gravitational Potential Energy

Physics

definition

Gravitational Potential (V)

The gravitational potential (V) is the gravitational potential energy (U) per unit mass: where m is the mass of the object. Potential energy is equal (in magnitude, but negative) to the work done by the gravitational field moving a body to its given position in space from infinity.

example

Change in gravitational potential energy as work done by gravitational force

Example: If is radius of the earth and is work done in lifting a body from the ground to an altitude , the calculate the amount of work which should be done in lifting it further to twice that altitude?

Solution:
work done is equal to change in PE

work done in lifting body from to
