Find the gravitational potential energy of 2.5 kg mass kept at a height of 15 m above the ground. The force of gravity on mass 1 kg is 10 N.

Open in App

Solution

Answer:
Mass m = 2.5 kg
Gravitational potential energy is the work done against force of gravity ¡s stored in the body at a height
h.
P.E = U = mgh
U = 2.5 × 10 × 15
U = 25/10 × 10 × 15 = 375 j
