Kinetic energy - Wikipedia
https://en.wikipedia.org/wiki/Kinetic_energy
WebThe kinetic energy is equal to 1/2 the product of the mass and the square of the speed. In formula form: where is the mass and is the speed (magnitude of the velocity) of the body. In SI units, mass is measured in kilograms, speed in metres per second, and the resulting kinetic energy is in joules .
