Message	"at a dead stop, the tire patch is very large, therefore more grip to get the car moving..." according to accepted physics and the formula for frictional force, that is not true. the normal force (Fn) is constant (the weight of the car is not changing), and the coefficient of friction is the same (assuming you are using the same tire compound). Later, Matt Any Ohio Zer's hit me up on AIM, mkddoc or PearlS14OH. Email at Mkddoc@aol.com

I did take the SAT however. - Kenny 14 psi 23:11:24 01/07/04 Congratulations. I have a Ph.D. in physics... - Technomancer 09:27:00 01/08/04 Okay. - Kenny 14 psi 10:47:01 01/08/04 ok - Technomancer 11:40:05 01/08/04 I will. - Kenny 14 psi 11:46:09 01/08/04
