I read in arons (sorry don't have the specific
reference) earlier today the
section on introducing Newton's laws and
specifically the concept of inertia
and the effects of forces on a body's motion. He
recommends a 50 lb piece of
dry ice on a sheet of glass. (!)
Has anyone done this? How big is the sheet of
glass? How big is 50 lbs of
dry ice? I am not sure where I will obtain these
things but the idea is a
great one...much better than 1 dimensional pasco
carts or even an air table
(since the pucks have such low mass). Are there
similar but easier things
folks have tried?
thanks for the help
Justin
