About Kinetic and potential energy calculator
Kinetic energy is 1/2 x m x v squared, and gravitational potential energy is m x g x h. Enter mass, speed and height to compare both, find the speed an object reaches when it falls, and see its momentum (m x v). Speed counts squared, so doubling it quadruples the kinetic energy.

Frequently asked questions
Why does doubling speed quadruple kinetic energy?
Because speed is squared in the formula 1/2 m v squared. Twice the speed gives four times the energy, which is why high-speed crashes are far more destructive.
