Lecture 08 — Rotation

Learning objectives

Students should be able to:

  • Describe rotation using angular position, velocity and acceleration, and relate them to the linear motion of a point on the body.
  • Calculate moments of inertia and torques, and use Στ = Iα to find angular accelerations.
  • Use work, power and energy methods for rotating and rolling bodies.
  • Use angular momentum and its conservation, including when the moment of inertia changes.
