Where KE is kinetic energy in joules m is mass in kilograms and v is velocity in meters per second.
Physics formulas energy. We started with the chemical energy in the gasoline and ended up with a bunch of heat plus the chemical energy in the combustion products. The work-energy which we have learnt is the theorem that is the work done by the net force on an object equals the change in kinetic energy of the object. Kinetic Energy Joules 12 x mass kg x velocity2 ms GPE Joules mass kg x gravitational field strength Nkg x.
