Kinetic Energy Calculator

Kinetic energy is the energy that an object possesses due to its motion. It is a fundamental concept in mechanics, quantifying the work needed to accelerate a body of a given mass from rest to its stated velocity.

Our calculator uses the classic kinetic energy formula to give you an instant result. Simply enter the object's mass in kilograms (kg) and its velocity in meters per second (m/s) to get its kinetic energy in Joules (J).

Example:

A 1000 kg car moving at 20 m/s (which is 72 km/h) has a kinetic energy of 0.5 * 1000 kg * (20 m/s)² = 200,000 Joules.
