Determine the amount of potential energy of a 5.0-n book that is moved to three different shelves on a bookcase . the height of each shelf 1.0m, 1.5m, 2.0m

Potential energy is the energy that is stored in an object due to its position relative to some zero position. It is calculated by the expression PE = mgh where mg is the weight of the book and h is the height. It is calculated as follows:

PE = 50(1) = 50 J
PE = 50(1.5) = 75 J
PE = 50(2) = 100 J
