In this lesson on rotational motion, we explore essential definitions such as angular displacement and angular velocity. We’ll demonstrate how to determine the direction of angular velocity using the right-hand rule: by curling your fingers in the direction of rotation, your outstretched thumb points in the direction of angular velocity. We'll also cover angular acceleration and its relation to linear variables, including the moment of inertia, torque, and the correspondence between linear and rotational motion. Engaging problems and activities will help reinforce these concepts.
