Question
An object is falling freely from a height x. After it has fallen a height `pi/2` , it will possess :
Options
only potential energy
only kinetic energy
half potential and half kinetic energy
less potential and more kinetic energy
Solution
During the free fall, potential energy is gradually converted into kinetic energy. At half of the maximum height, energy is equally distributed in the form of potential and kinetic energy.
Therefore, the answer is, (c) Half potential and half kinetic.
