# work done by gravitational force and potential energy

Not what you're looking for?

A 0.60 kg ball is dropped out of a window that is 6.1 m above the ground. The ball is caught by a person whose hands are 1.5 m above the ground.

a.) How much work is done on the ball by its weight?

What is the gravitational potential energy of the basketball, relative to the ground, when it is
b.)released and c) caught?

d.)How is the change (PEf-PEo) in the ball's gravitational potential energy related to the work done by its weight?

##### Solution Summary

The solution shows how to calculate the work done by the gravitational force on the ball. Furthermore, it explains the relationship between the work done and the change of potential energies of the ball.
