What is the energy that an object has because it is moving?

Explanation:
Energy due to motion is called kinetic energy. It is the energy an object has because it is moving, and it depends on both its mass and its speed (KE = 1/2 m v^2). This is why the correct choice fits best: kinetic energy is specifically the energy associated with motion, not stored energy from position (potential energy), and not simply mass or speed themselves. For example, a 1000 kg car moving at 20 m/s has about 200,000 joules of kinetic energy, and if it speeds up to 40 m/s, its kinetic energy jumps to about 800,000 joules—showing how energy tied to motion increases with speed and mass.
