A lab demo with two green lab carts that roll on a black metal track is presented. The demonstration shows that when a spring is released, the carts (one with twice as much mass as the other) that were originally placed next to one another recoil and roll across the track. Explain, in detail, how momentum is conserved when the carts were originally at rest and then after their collision they are in motion, one cart with half the speed of the other?

Helmholtz Free Energy

The Helmholtz free energy is a thermodynamic potential used to calculate the measure of useful work from a closed system. This system is kept at constant temperature and volume. German physicist Hermann Helmholtz introduced this concept in 1882.
