Chapter 8: Angular Motion and Statics Difficulty Level: At Grade Created by: CK-12 CK-12 Physics - Intermediate Read Resources Details Credit: CK-12 Foundation License: CC BY-NC 3.0 [Figure1] We have looked at circular motion using the same measures as linear motion. To look at rotation in more detail, though, we need to work in rotational units - measuring the angle rotated through, the angular sped, and angular acceleration. Chapter Outline 8.1. Angular Momentum8.2. Torque8.3. Two Conditions of Equilibrium8.4. Applications of Equilibrium Conditions Chapter Summary Angular momentum is defined as the product of rotational inertia and angular velocity. Torque is defined as , where the angle is the angle between the lever arm and force . The symbol for torque is the Greek letter tau By definition a counterclockwise torque is positive and a clockwise torque is negative. Two conditions of equilibrium: Translational equilibrium: Rotational equilibrium: Image Attributions ^ Credit: CK-12 Foundation; License: CC BY-NC 3.0 Description Covers angular momentum and torque along with translational and rotational equilibrium.
