Question

What is the purpose of kinetic energy?

Answer 1

1. $K=\frac{1}{2}m{v}^2$, where $K$ is kinetic energy,$m$ is mass and $v$ is the speed of the body
2. A body that is moving is due to kinetic energy, i.e., it is the energy stored in a body which is due to the virtue of motion.
3. The purpose of the kinetic energy to keep the body in motion.
4. Kinetic energy gives rise to vibration in a body (which becomes a source of Internal energy).
