Answer
- Energy possessed by a body by the virtue of its motion.
Explanation:
The energy which a body possesses by virtue of being in motion is called as kinetic energy.
If we want to stop a moving body then we must do some work on the body to stop it which means that a moving body possesses energy because of motion.
If an object of mass m moving with the velocity v, The kinetic energy is defined as,
$\text{K.E}=\frac{1}{2}\text{mv}^2$
