Circular motion


Units of angular displacement Radians
To convert degrees to radians Divide by 360 and multiply by 2π
To convert radians to degrees Divide by 2π and multiply by 360
Symbol for angular displacement ϴ
The rate of change of angular displacement is called Angular Velocity
The symbol for angular velocity ω
We can calculate ϴ by arc/radius
The equation for ϴ is ϴ = s/r
We can calculate ω by rate of change of ϴ
The equation for ω ω=Δϴ/Δt
How many radians in a circle
The time for an object to complete a circle is 2π/ω
The time for one complete rotation is called the Period (T)
The equation for the period(T) is T= 2π/ω
