Kinetic energy
Kinetic energy is energy that a body has as a result of its speed.
~ ~ ~ ~ ~ ~ ~ ~ ~ ~
It is formally defined as work needed to accelerate a body from rest to a velocity v. Having gained this energy during its acceleration, the body maintains this kinetic energy unless its speed changes. The same amount of work would also be required to return the body to a state of rest from that velocity.
