Work –Energy
... Let the mass drop and measure the final velocity of the system using a photogate timer (velocity = [card length]/time). Compute the final kinetic energy of the system, using Msystem. The cart should go through the photogate just after the mass hits the cushion. Show calculations and record below. ...

What is energy?
... Assuming there is no input of energy (closed system), when energy is converted from one form to another, the amount of useful energy in the system decreases. Entropy is the tendency toward an increase in randomness and disorder in a closed system. ...

... Version 1 A force is conservative when the work it does on a moving object is independent of the path between the object’s initial and final positions. Version 2 A force is conservative when it does no net work on an object moving around a closed path, starting and finishing at the same point. ...
