5.2 Connecting Linear and Rotational Motion

Describe the linear motion of a point on a rotating rigid system that corresponds to the rotational motion of that point, and vice versa.

• For a point at a distance r from a fixed axis of rotation, the linear distance s traveled by the point as the system rotates through an angle is given by the equation
• Derived relationships of linear velocity and of the tangential component of acceleration to their respective angular quantities are given by the following equations:
• For a rigid system, all points within that system have the same angular velocity and angular acceleration. BOUNDARY STATEMENT Descriptions of the directions of rotation for a point or object are limited to clockwise and counterclockwise with respect to a given axis of rotation. | AP Physics 1: Algebra-Based Course and Exam Description TOPIC 5.3 Torque | AP Physics 1: Algebra-Based Course and Exam Description
