Question

A body is falling from a height $h$,after it has fallen from a height $h/2$,it will possess.

• A. only potential energy
• B. only kinetic energy
• C. half potential energy and half kinetic energy
• D. more kinetic and less potential energy

Answer 1

The correct option is C

half potential energy and half kinetic energy

1. If a body falls from a height of $h/2$ it will possess half potential energy and half kinetic energy.
2. When the body is at height h, its potential will be a hundred percent and kinetic energy will be zero.
3. In the same way, when the body reaches the ground its potential energy will be zero and kinetic energy will be maximum.
4. At height $h/2$ both kinetic energy and potential energy of the body will be half.

Hence, option C is correct.
