Kinetic Energy Calculator
Calculate the kinetic energy of a moving object from its mass and velocity.
Kinetic energy
100 J
Enter an object's mass and velocity to find its kinetic energy using KE = ½ m v². The result is shown in joules.
How to use
- Enter the mass of the object in kilograms.
- Enter its velocity in meters per second.
- Read the kinetic energy in joules below.
Frequently asked questions
- What is the kinetic energy formula?
- Kinetic energy KE = ½ × mass × velocity². Doubling the velocity quadruples the kinetic energy.
- What unit is the result?
- The energy is given in joules (J) when mass is in kilograms and velocity in meters per second.
