An object of mass 5 kg falls from a height of 5 m above the ground. The loss of potential energy of the mass is :
Given,
Mass = 5kg
Height = 5m
Let g = 10 ms-2
Potential energy stored in a body of mass m and height ‘h’ will be given by
= m × g × h
= 5 kg×10 ms-2×5m
= 250 J
When the mass falls completely, same potential energy is lost = 250 J
