Question

A body is falling from a height of h. After it has fallen a height `"h"/2`, it will possess

Options

  • only potential energy

  • only kinetic energy

  • half potential and half kinetic energy

  • more kinetic and less potential energy

MCQ

Solution

more kinetic and less potential energy

Explanation:

When a body falls from a height `"h"/2` its potential energy becomes half (as potential energy = mgh ). The rest half of the initial potential energy gets converted into kinetic energy.
Hence, the body will possess half potential energy and half kinetic energy.
