wikiHow Calculating Kinetic Energy Practice Problems Kinetic energy is the energy an object possesses by virtue of its motion. The kinetic energy of an object depends on its mass and velocity. To calculate the kinetic energy of an object, you can use the following formula: Kinetic energy (KE) = (1/2) x mass (m) x velocity (v)^2 1.
