Question

A freely falling object eventually stops on reaching the ground. What happenes to its kinetic energy?

Answer

When the object hits the ground and stops, its kinetic energy is not lost but transformed into other forms of energy:

  1. Heat Energy: Generated due to the impact and friction.

  2. Sound Energy: Produced by the collision (noise).

  3. Potential Energy: Consumed in changing the shape (deformation) of the object or the ground.
