Review

One of the simplest situations in which an object follows a curved trajectory is \(\textit{uniform circular motion}\), or motion around a circular path at a constant speed. We saw in Section 3-8 that in uniform circular motion, the acceleration at any point around the circle is directed toward the center of the circle (that is, it is \(\textit{centripetal}\)) and has a magnitude \(a_\mathrm{cent}\) that depends on the object’s speed \(v\) and the radius \(r\) of the circle:
