Question

A 3.75 kg ball is lifted from the floor to a height of 1.5 m above the floor. What is its increase in potential energy?

Answer 1

We can use a simple equation to calculate the increase in gravitational potential energy. PE = mgh m is the mass of the object g is the acceleration due to gravity h is the change in height PE = mgh PE = (3.75 kg) (9.80 m/s^2) (1.5 m) PE = 55.1 Joules The increase in gravitational potential energy is 55.1 Joules.
