where does the energy of a freely falling body go when it hits the ground?
Asked by shivani jadhao | 23 Nov, 2013, 09:19: PM
answered-by-expert Expert Answer

When an object falls freely towards the ground, its potential energy decreases and kinetic energy increases.

As the object touches the ground, all its potential energy gets converted into kinetic energy. As the object hits the hard ground, all its kinetic energy gets converted into heat energy and sound energy.

It can also deform the ground depending upon the nature of the ground and the amount of kinetic energy possessed by the object.
