Unformatted text preview: Centripetal Force Examples Physics 6A Prepared by Vince Zaccone For Campus Learning Assistance Services at UCSB Prepared by Vince Zaccone For Campus Learning Assistance Services at UCSB Ride your bike around a curve and you will notice that if you go too fast, your tires will slip and you will fall. Why does this happen? Prepared by Vince Zaccone For Campus Learning Assistance Services at UCSB Ride your bike around a curve and you will notice that if you go too fast, your tires will slip and you will fall. Why does this happen? Static friction is not strong enough to keep your tires from slipping on the pavement. Prepared by Vince Zaccone For Campus Learning Assistance Services at UCSB v 2 ) d v 2 ) c v ) b 2 v ) a Ride your bike around a curve and you will notice that if you go too fast, your tires will slip and you will fall. Why does this happen? Static friction is not strong enough to keep your tires from slipping on the pavement. OK, lets say you are riding your bike around a level curve and your maximum speed is v when the radius of the curve is R. Here are a couple of multiple choice questions: 1) What is your maximum speed if the radius of the curve is 2R? Prepared by Vince Zaccone For Campus Learning Assistance Services at UCSB We will need to find a formula relating v and R. A diagram may help.
