MCQ
What is kinetic energy?
  • A
    Energy possessed by a body by the virtue of its motion.
  • B
    Energy possessed by a body by the virtue of its shape.
  • C
    Energy possessed by a body by the virtue of its size.
  • D
    None.

Answer

  1. 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,

$\text{K.E}=\frac{1}{2}\text{mv}^2$
