Kinetic Energy
Kinetic energy is the energy an object has because of it's motion. This energy can be converted into other kinds of energy, such as gravitational or electric potential energy. It is defined as the work needed to accelerate a body of a given mass from rest up to its stated velocity.
Having gained the energy during it's acceleration, the body maintains kinetic energy unless the speed is changed. The same amount of work is done by the body in decelerating from it's current speed to a state of rest.
This could be seen as something rolls down a hill, like at the Jaffa run in Dunedin.
