1. A body is falling from a height h. After it has fallen a height h 2 , it will possess (a) only potential energy (b) only kinetic energy (c) half potential and half kinetic energy more kinetic and less potential energy

• Soln:

Answer is (c) half potential and half kinetic energy

Explanation:

When body is at height h, its potential will be hundred percent and kinetic energy will be zero. In the same way when body reached ground its potential energy will be zero and kinetic energy will be maximum. At height h/2 both potential energy and kinetic energy of the body will be half.
