Determine the amount of potential energy of a 5.0Kg book that is moved to three shelves on a bookcase. The height of each shelf is 1.0 meters, 1.5 meters, and 2.0 meters.

The potential energy is 50 joules, 75 joules and 100 joules

Explanation:

Potential energy is the energy stored in an object by virtue of its position relative to others objects. For example a heavy ball placed at an elevated position.

The potential energy is given as:

Where is the potential energy of the object, m is the mass of the object, h is the height in which the object is placed and g is the acceleration due to gravity.

For 1.0 meters:

m = 5.0 kg   g = 10 m/s²    h = 1 meters

The potential energy is 50 joules

For 1.5 meters:

m = 5.0 kg   g = 10 m/s²    h = 1.5 meters

The potential energy is 75 joules

For 2.0 meters:

m = 5.0 kg   g = 10 m/s²    h = 2 meters

The potential energy is 100 joules
