Use the formula: angular velocity = change in angle ÷ time
Write it as ω = Δθ / Δt
Measure the angle in radians
Measure the time in seconds
Calculate the difference in angle between the start and end positions
Divide the angle change by the time taken
Use the result in radians per second
For circular motion, use ω = v / r
In this formula, v is linear speed and r is radius
If you know frequency, use ω = 2πf
If you know period, use ω = 2π / T
Make sure all units are consistent before calculating
