AP Physics 1 & 2 Describing Circular Motion
II. Mechanics: Lecture 12 | 7:18 min
Radial motion is the motion along a circular path; it has a special kind of acceleration, which youll learn about next time. Up until now weve dealt with linear motion, but now were introducing a new form of motion with its own set of equations. Circular motion is a relatively special topic in mechanics because, up until now, weve only been concerned with time, but never its reciprocal. Frequency is a big part of circular motion, and can be pretty easy to confuse it with the period of a circular system. Be sure to take note of this pitfall!
