# Problem: For each of the following processes, does the potential energy of the object(s) increase or decrease?(b) Water is pumped from ground level to the reservoir of a water tower 30 m above the ground.

###### FREE Expert Solution

In terms of height, the potential energy (P.E.) of an object is given as follows:

$\overline{){\mathbf{P}}{\mathbf{.}}{\mathbf{E}}{\mathbf{.}}{\mathbf{=}}{\mathbf{mgh}}}$

m = mass; g = acceleration due to gravity; h = distance of the object to the ground
