KINETIC ENERGY
Kinetic energy is the energy of mass in motion. The kinetic energy of an object is the energy it has
because of its motion.

which it is mov

F is force, m is mass and a is acceleration. The math behind this is quite simple. If you double
the force, you double the acceleration, but if you double the mass, you cut the acceleration in
half. When a constant force acts on a massive body, it
