Joule Calculator

Enter the mass and velocity into the joule calculator. The calculator will display the total kinetic energy of that object in Joules. You can further convert this to another unit of measure.

Joule Fromula

The following formula is used to calculate the total energy in Joules a moving object has.

(K) = 1/2 *(m)*(v)^2

  • Where K is kinetic energy in Joules (J)
  • m is mass (kg)
  • and v is velocity (m/s)

Joule Definition

A joule is defined as the standard SI unit for energy.

How to calculate joules?

How to calculate a joule

  1. First, measure the mass of the object

    Using a scale or formula, determine the mass of the object.

  2. Next, measure the velocity

    Measure or determine the velocity of that same object.

  3. Calculate

    Calculate the total number of joules of kinetic energy the object has using the information above.


What is a joule?

A joule is the SI unit for energy. Energy is a measure of the activity of a substance.

What is kinetic energy?

Kinetic energy is a type of energy that comes from the movement of objects.
