Arrange the objects in order from least to greatest potential energy. Assume that gravity is constant. (Use PE = m * g * h.)

a 15-kilogram stone

found at a height of

3 meters

10 kilograms of water

stored at a height of

9 meters

a 1-kilogram ball located

20 meters in the aira box of books weighing

25 kilograms placed on

a shelf 2 meters high

The following are the proper arrangements of objects that have the greatest to the least amount of potential energy:

a 1-kilogram ball located 20 meters in the air

10 kilograms of water stored at a height of 9 meters

a 15-kilogram stone found at a height of 3 meters

a box of books weighing 25 kilograms placed on a shelf 2 meters high

Potential energy is dependent on the distance at which an object falls in spite of the presence of a constant gravity.
