Question

Determine the amount of potential energy of a 5 Newton's book that is moved to three different shelves on a bookcase. The height of the shelves is 1.0 meter,1.5 meter, and 2.0 meter

Answer 1

5 Joules, 7.5 Joules and 10 Joules respectively

Step-by-step explanation:

Potential energy due to gravity is given by mass*gravity*height or weight*height(As weight= mass*gravity)

The potential energy at the height of 1 meters = 5*1 = 5 Joules

The potential energy at the height of 1.5 meters = 5*1.5 = 7.5 Joules

The potential energy at the height of 2 meters = 5*2 = 10 Joules
