Unit 5 · Torque and Rotational Dynamics

Chapter 5.1

Rotational Kinematics

Every point on a spinning record shares one angular velocity, yet the rim moves faster than the middle. Swap angle for position and all of kinematics replays itself.

lesson 15 of 18

By the end

  1. 01Describe rotation with angular displacement, angular velocity, and angular acceleration in radians
  2. 02Apply the constant-angular-acceleration equations and read angular graphs by slope and area
  3. 03Connect a point's arc length, speed, and tangential acceleration to the angular quantities through its distance from the axis
