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.

What we have learnt
- Angular velocity is defined as the rate of change of angular displacement over time.
- Angular acceleration is the rate of change of angular velocity with respect to time.
- The core equations of angular motion parallel those of linear motion, aiding in the analysis and problem-solving of rotational dynamics.
Key Concepts
- -- Angular Velocity
- The rate at which an object rotates around a specific point or axis, typically measured in radians per second (rad/s).
- -- Angular Acceleration
- The rate of change of angular velocity over time, measured in radians per second squared (rad/sĀ²).
- -- Uniform Angular Motion
- A scenario where angular velocity remains constant, resulting in zero angular acceleration.
- -- NonUniform Angular Motion
- A scenario where angular velocity changes over time, indicating the presence of angular acceleration.
- -- Equations of Angular Motion
- Mathematical expressions correlating initial and final angular velocities, angular displacement, and angular acceleration, similar to linear equations of motion.
