2. Angular Velocity and Angular Acceleration

Angular velocity quantifies the speed of an object's rotation around a given point, measuring how an angle changes over time. Angular acceleration indicates how angular velocity changes, representing the rate of speeding up or slowing down. This chapter explores these concepts in-depth, including their formulas, relationships, and applications in various fields such as machinery and planetary motion.
