Conceptual Questions: 1) There is an analogy between rotational and linear physical quantities. What rotational quantities are analogous to distance and velocity? 2) Define centripetal force. Can any type of force (for example, tension, gravitational force, friction, and so on) be a centripetal force? Can any combination of forces be a centripetal force?
