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)
