Question

Define kinetic energy. Give two examples of objects possessing kinetic energy.

Answer 1

1. Kinetic energy is defined as the energy possessed by a body due to the virtue of its motion.
2. Its SI unit is Joule (J).

$Kineticenergy=\frac{1}{2}xmx{v}^2$

Where, 'm' is the mass of the object, and 'v' is the velocity of the object.

Examples of kinetic energy.

1. Flying airplane.
2. A person walking or running.
