1. Chapter 11 Rolling, Torque, and Angular Momentum
In this chapter we will cover the following topics:
-Rolling of circular objects and its relationship with friction Redefinition of torque as a vector to describe rotational problems that are more complicated than the rotation of a rigid body about a fixed axis Angular Momentum of single particles and systems or particles Newton’s second law for rotational motion Conservation of angular Momentum Applications of the conservation of angular momentum
