Thank you for everyone who had responded. I figured that theWe did a nice lab with golf balls which were struck by a metal (brass?)
inertia and friction would play a factor, but I was hoping that it
play that big of a factor.
At my school, we don't have photogates...unfortunately. I was hoping
able to do without them.
I do like the idea of "Newton's golf" by John Denker
(http://www.av8n.com/physics/img48/golf.png) and plan on testing out
idea. Can anyone suggest where I might be able to find large metal
bearings? If I can't find metal balls, I may test it using golf
