Question

When an object falls on the ground, its kinetic energy is changed to sound and heat energy. But where did the sound and heat energy go? Is it destroyed?

Answer 1

As we know that the energy can neither be created nor be destroyed by law of conversation of energy. In simple words energy depends on type of object. For eg. if object is elastic it means that object can bounce. So in this bouncing case the energy is used in bouncing of object and gets utilised there. And now if object is hard (like plastics or other things like that), most of the energy can be utilised in breaking of object and left over energy is lost in universe. And if object is completely inelastic (like bricks) whole energy goes in smashing or breaking of object.

Answer 2

Sound and Heat energy goes to the atmosphere. Energy can't be destroyed as we know that energy can neither be created nor be destroyed but it can change from one form to another form.

So, heat energy dissolved into the atmosphere, and sound energy also goes into the atmosphere.
