AP Physics 1: Rotational Kinematics Review

The video tutorial covers key concepts in rotational kinematics for the AP Physics One exam. It begins with an introduction to angular velocity, its symbol, and units. The tutorial then explains angular acceleration, its relationship with linear motion, and introduces uniformly angularly accelerated motion equations. The concept of constant angular velocity and uniform circular motion is discussed, highlighting the difference between angular and tangential velocities. The video also explores centripetal force and acceleration, emphasizing their role in circular motion. Problem-solving using free body diagrams is demonstrated, focusing on forces like tension and gravity. Finally, the tutorial explains the relationship between period and frequency, providing equations and clarifying the role of radians.
