प्रश्न
A body is falling from a height of h. After it has fallen a height `"h"/2`, it will possess
विकल्प
only potential energy
only kinetic energy
half potential and half kinetic energy
more kinetic and less potential energy

उत्तर
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.
