Kinetic Energy Calculator

In terms of physics, Kinetic Energy 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). The common symbols of representation are KE, Ek, or T. It is directly proportional to the mass of the object and to the square of its velocity: K.E. = 1/2 mv^2. This online kinetic energy calculator helps you to calculate the Kinetic Energy (KE), Mass or Velocity from the other two known values.

Kinetic Energy:

Ek = 1/2 (mv2)

Mass:

m = Ek / 1/2 (v2)

Velocity:


Where, m = Mass, v = Velocity.

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
