Kinetic energy is the energy that any object with mass has simply because it is moving. If an object is not moving, it has no kinetic energy.
In classical mechanics, kinetic energy (KE) is equal to half of an object''s mass (1/2*m) multiplied by the velocity squared. For example, if a an object with a mass of 10 kg (m = 10 kg) is moving at a velocity of 5 meters per second (v = 5 m/s), the kinetic energy is equal to 125 Joules, or (1/2 * 10 kg) * 5 m/s2.
