In a class demonstration, a bicycle wheel was held on an axle and spun. The result came to be that the wheel while rotating held a vertical position while holding it by a string attached to the end of the axle. After the wheel stopped rotating its vertical position ceased and the wheel attained...
My question is how can Ac (centripetal acceleration) be both inversely related to radius and directly related in two equations:
1) Ac = V2/r
2) Ac = 4pi2r/T2
In the first equation Ac is inversely proportional to radius in the second one Ac is directly proportional to radius. Why and how is...
I'm currently a student in high school taking AP Physics and I'm interested in a book that would contain problems and detailed solutions to each problem. Please give me some recommendations to what book(s) I should look into.
