When an object is lifted 10 feet off the ground, it gains a certain amount of potential energy. If the same object is lifted 30 feet off the ground, its potential energy is .

3 times as much the potential energy

Explanation:

Potential energy is the energy possessed by an object by virtue of its position.

m= mass of object

g = acceleration due to gravity

h = height of an object  

When same object with same is lifted from 10 feet to 30 feet. The height has increased 3 times , thus the potential energy will also get 3 times as much.
