As a car rolls down a hill, the motion and gravitational potential energy(GPE) will be equal when the kinetic energy is equal to the potential energy.
Gravitational force.
Whenever anything falls down, rolls downward, etc., gravitational potential energy will be converted into kinetic energy.
Before it rolls downhill, it has gravitational potential energy. As it rolls downhill, part of this potential energy is converted into kinetic energy (including rotational energy); due to friction, this will soon be converted into waste energy, mainly heat.
Dropping something from a height.
Any time something falls, rolls, or slides down, gravitational potential energy is converted into kinetic energy.
Assuming it just rolls down a slope, without the engines working: gravitational potential energy will be converted to kinetic energy. The kinetic energy will eventually be converted to heat energy.

it gains kinetic energy as the can rolls back to you.

10 rolls of 10 pennies is 10$
its motion and accelaration are in opposite directions
