Enter the total kinetic energy and the mass into the calculator to determine the velocity.

Kinetic Energy to Velocity Formula

The following equation is used to calculate the velocity from kinetic energy.

V = SQRT( KE * 2 / M)

  • Where V is the velocity (m/s)
  • KE is the kinetic energy (Joules)
  • M is the mass (kg)

To calculate the velocity from kinetic energy, multiply the energy by 2, divide by the mass, then take the square root of the result.

How to Convert Kinetic Energy to Velocity?

Example Problem:

The following example outlines the steps and information needed to convert kinetic energy to velocity.

First, determine the kinetic energy. In this example, the kinetic energy is found to be 500 Joules.

Next, determine the mass. For this problem, the mass is found to be 25 kg.

Finally, calculate the velocity from kinetic energy using the formula above:

V = SQRT( KE * 2 / M)

V = SQRT( 500 * 2 / 25)

V = 6.324 m/s
