• The demonstration comes with :
  • A low-friction light pulley.
  • A meter stick and a stop watch.
  • Two LARGE Masses of M = 200 grams each AND two little masses of m = 5 grams each, which can be transferred.
• Example: 1(M) versus 1(M) plus 2(m) on opposing side.
  • Total mass of both sides together = 410 grams
• The image shows each 200 gram mass (2M) containing the same number of 5 gram masses (2m).
• A stopwatch is used to measure the time it takes one side to fall 1 meter.
