During free fall work done is negative of change in potential energy.Is this only valid during free fall or is applicable everytime?

Expert Answer:

Dear student,
 
Gravitational energy is the potential energy associated with gravitational force. If an object falls from one point to another point inside a gravitational field, the force of gravity will do positive work on the object, and the gravitational potential energy will decrease by the same amount.
 
Hope this helps.
