Analyzing circular motion with N2L
So to analyze the forces involved in circular motion, we will orient our xy axes along the
centripetal and tangential directions. This is a very important point. Then we will
resolve all forces into components along the
How fast can you go over a hill with radius of curvature R = 10m without flying off?
Consider the diagram below, with forces labelled, and axes drawn.
So write out N2L using this fact, and solve for v.
As you may know by experience, the faster you go over
Motion
Consider a car driving along a circular track with radius r = 5m, at a constant speed of v =
10m/s. What is its acceleration (give magnitude and direction) when it is at the top of the
circle?
The acceleration would be:
