Kinetic Energy Calculator

The kinetic energy (KE) of an object is the energy that it possesses due to its motion. Use our online kinetic energy calculator to calculate KE in Joules based on the values of mass and velocity.

Kinetic Energy:

Ek = 1/2 (mv2)

Mass:

m = Ek / 1/2 (v2)

Velocity:


Where, m = Mass, v = Velocity.

Apart from KE calculation, this kinetic energy calculator also helps you to calculate the mass and velocity of an object based on either of the two known values. KE is defined as the work needed to accelerate a body of a given mass from rest to its current velocity and its SI unit is joule (J).It is directly proportional to the mass of the object and to the square of its velocity. The difference between Kinetic Energy and Potential energy is that, Potential Energy is the stored energy in an object due to its position whereas, KE is the energy which a body possesses because of its motion.

Example:

An object with mass 30 kg and velocity 20 m/s has a kinetic energy

Step 1 :

Kinetic Energy (KE) = 1/2 mv2
= 1/2 (30 x 20 x 20)
= 6000 Joules
