About Angular Velocity

Angular velocity (ω) is the rate of change of angular displacement with respect to time. It describes how fast an object rotates around a fixed axis and is measured in radians per second (rad/s).

The SI unit of angular velocity is radians per second (rad/s). Other common units include degrees per second (deg/s), revolutions per minute (RPM), and revolutions per second (RPS).

Common Applications:

  • Mechanical engineering and design
  • Robotics and automation
  • Automotive engineering (engine RPM)
  • Industrial machinery and motors
  • Physics and engineering education
