Description
I will present six center of mass demonstrations using inexpensive equipment:
a. Bet your fingers will meet in the middle of a meterstick.
b. Balancing a quarter on a dollar bill.
c. Bet you can't get out of a chair.
d. Removing one support leg from a Jenga block structure.
e. Cookie tin rolling uphill.
f. Balancing a soda can on its edge.
I will also provide a link to a Google document that has numerical problems for the meterstick and Jenga block demonstrations as well as a problem that asks students to find the height of liquid in a soda can that minimizes the center of mass. (Note: the soda can problem is not original.)
