Electric potential on one side of the closed circuit is applied and this causes the electrons to move to a position of lower potential. Imagine this as when you raise an object above the ground and release it. It moves from its higher potential energy position above the ground to its lower potential energy position.
<em>Kinetic (mechanical) energy</em>
Formula for momentum is mass times velocity so you do 52 kg times 5 m/s and that equals 260 kg x m/s
