About Angular Velocity

Angular velocity is a measure of how quickly an object rotates or revolves. It is the rate of change of angular displacement and is a vector quantity (having both magnitude and direction).

Units of Angular Velocity
  • Radians per second (rad/s): The SI unit of angular velocity
  • Degrees per second (°/s): Common in many applications
  • Revolutions per minute (RPM): Used in engineering applications
  • Hertz (Hz): Frequency in cycles per second
Formulas
  • From revolutions and time: ω = 2π × (revolutions / time)
  • From linear velocity and radius: ω = v / r
  • From angle and time: ω = θ / t
  • From frequency: ω = 2π × f
  • From RPM: ω = RPM × (2π/60)
Conversions
  • 1 rad/s = 57.2958 deg/s
  • 1 rad/s = 9.5493 RPM
  • 1 RPM = 0.1047 rad/s
  • 1 Hz = 6.2832 rad/s
  • 1 deg/s = 0.0175 rad/s
Applications of Angular Velocity

Understanding angular velocity has many practical applications:

  • Engineering: Design of motors, turbines, and rotating machinery
  • Physics: Analysis of rotational dynamics and orbital motion
  • Astronomy: Study of celestial body rotation and revolution
  • Robotics: Control of rotational movement in robotic joints
  • Sports Science: Analysis of athletic movements (e.g., golf swing, baseball pitch)
  • Manufacturing: Control of cutting speeds in lathes and mills
