Centripetal Forces: Rotational Motion
Circular and rotational motions are widespread both in nature and in man-made machines, from merry-go-rounds to the orbits and spins of planets. To analyze and model such types of motion, we need some special tools: the linear kinematics and dynamics presented in Chapter 5 need to be extended to rotational motion. In a nutshell, this is what the present chapter will begin to look into.
