A rock is at the top of a 20 meter tall hill. The rock has a mass of 10 kg. How much potential energy does it have?

Explanation:

The potential energy of a body can be found by using the formula

PE = mgh

where

m is the mass

h is the height

g is the acceleration due to gravity which is 9.8 m/s²

PE = 10 × 9.8 × 20

We have the final answer as
