MCQ
A body is falling a height $h$. After it has fallen a height $\frac{\text{h}}{2}$. it will possess
  • A
    Only potential energy
  • B
    Only kinetic energy
  • ✓
    Half potential energy and half kinetic energy
  • D
    More kinetic and less potential energy
✓

Answer

Correct option: C.
Half potential energy and half kinetic energy
When the body is height $h$; its potential energy is at maximum and kinetic energy is zero. When the body hits the ground, its potential energy becomes zero and kinetic energy is at maximum. At mid$-$way i.e., half the height; its potential energy becomes half of the maximum potential energy and same happens to the kinetic energy.
