Determine the amount of potential energy of a 5-newton book that is moved to three different shelves on a bookcase. the height of each shelf is 1.0 meters, 1.5 meters, and 2.0 meters.

Potential energy is defined as

here we have

mg = weight = 5 N

now for different heights we can say

U = mgh

so potential energy in all three shells will be different and increases with height

explanation:

newton's third law, for every action there is an equal and opposite reaction.

the small 0.38-kg slider is known to move from position a to position b along the vertical-plane slot. determine (a) the work done on the body by its weight and (b) the work done on the body by the spring. the distance r = 0.70 m, the spring modulus k = 154 n/m, and the unstretched length of the spring is 0.53 m
