Study Notes

Physics rotational motion is a topic that describes the relationships between the angle of rotation, angular velocity, angular acceleration, and time. In this article, we will be focusing on the subtopics of angular acceleration, torque, angular displacement, angular velocity, and moment of inertia.

Angular acceleration is the rate of change of angular velocity. It is denoted as α and is given by the equation:

α = ω/τ

Angular velocity, on
