Kinetic energy is the energy that an object possesses due to its motion. It is defined as half of the product of the object''s mass and its velocity squared. In other words, the more massive an object is and the faster it moves, the greater its kinetic energy. The formula for kinetic energy is: Kinetic energy = 1/2 x mass x velocity^2
