A block of mass m1=2.4kg is connected to a second block of mass m2=1.8kg. When the blocks are released from rest, they move a distance of .5m at which point m2 hits the floor.

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.
