What's "Black Magic"?
What's the 7-8:1 Ratio?
How can I better energize a rubberband without making it more breakable? I was thinking of stretching it and keep it stretched overnight, but if you have any better ideas please say.
Rubber Band Car For Physics-- Any Help?
I'm building a rubber band car for physics and need as much help as possible. I'm by myself this time because I chose (and regret it). But, so far I have found this much out:
Stuff so far:
*Records/CD's are good because of large Diameter
*Heating...

2. Not really too sure, but here are some I know:
Fa=Fb*Cos(Theta)b
Fg=Fa*Sin(Theta)a+Fb*Sin(Theta)b

I'm completely clueless... We've never done anything in class with...
