1
New cards

  • define period


  • time taken for an object to complete one revolution


2
New cards

  • define frequency


  • number of revolutions completed per unit time


3
New cards

  • define angular velocity


  • rate of change of angle


4
New cards

  • state the formula for angular velocity

  • state the formula for angular velocity including period

  • state the formula for angular velocity including frequency


  • ω = θ/t

    • angular velocity (rads-1) = change in angle (rad) / time (s)

    ω = 2π/T

    • angular velocity (rads-1) = (2 × π) / period (s)

    ω = 2πf

    • angular velocity (rads-1) = 2 × π × frequency (Hz)
