Chapter 11: General Rotations
In the last chapter we studied rotational kinematics, rotational energy, and moment of inertia for objects rotating about a fixed axis. In this chapter we will begin by discussing the mathematical description of torque as a vector or cross product. We will also focus on general rotations such as when objects roll (rotate and translate).
