Kinetic Energy Calculator — Answer & Method

Calculate kinetic energy of a moving object.

Formula: Kinetic Energy

KE = ½mv²

m = Mass (kg)
v = Velocity (m/s)

Example Calculation

A 10 kg object at 5 m/s has kinetic energy of 125 joules.

Important limitation

Check the result against your specific circumstances before making a decision.

Key Facts

  • Kinetic energy is proportional to the square of velocity.
