Kinetic energy (KE) of an object is the energy that it possesses due to its motion. We can also define it as the work needed to accelerate an object of a given mass from rest to its stated velocity.

The object maintains its kinetic energy unless its speed changes. Kinetic energy is usually measured in units of Joules (J).

**Formula to calculate kinetic energy.**

Mass is the amount of matter present in a body and its SI unit is kilogram (Kg).

Velocity is an objectâ€™s speed in a particular direction its SI unit is meters per second (m/s).

**Example:**

Calculate the kinetic energy of a 60 Kg body travelling at 18 m/s.

Therefore, the kinetic energy of the body is 9720 joules.
