Lecture 20: Rotational kinematics and energetics
Objectives: In this lecture, students will learn to
- extend kinematics to rotational quantities
- relate angular velocity and acceleration to linear velocity and acceleration
- interpret the meaning of the quantity moment of inertia
- calculate moments of inertia using the parallel axis theorem
- define rotational kinetic energy
- explain rolling without slipping in terms of rotation about center of mass plus translation of center of mass
- apply energy conservation to problems involving rotation
