Do a little research about the "center of gravity" (CG) concept and bring a definition to our next class.
Also, consider the following problem:
A meter stick is used in an experiment, with the fulcrum located at the 28 cm point. If a 100 g mass balances when placed at the 15 cm point, what is the mass of the meter stick? Use the CG concept to solve this problem. Recall that the CG is the point where we can pretend that ALL of the mass of something is located.
Another question to consider. Regarding the CG of an object: how do you think an object's stability (resistance to falling or flipping over) is related to its CG?
One more: Think about the famous leaning tower in Pisa, Italy. Why do you suppose it does not fall over? Think in terms of the CG.
