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

Open in App

Solution

Kinetic energy is defined as the energy possessed by a body due to the virtue of its motion.
Its SI unit is Joule (J).
$K i n e t i c e n e r g y = \frac{1}{2} x m x v^{2}$
Where, 'm' is the mass of the object, and 'v' is the velocity of the object.
Examples of kinetic energy.
Flying airplane.
A person walking or running.
