You just have to use the corresponding equations from Newton's law for rotating objects. So simply: Product rule dz/dt=ω×z

Consider a rod held vertically with a pivot at its base. If the rod is allowed to fall to one side each point on the rod turns through the same angle in a given amount of time. This is shown in the diagram bellow: To say otherwise would be against all experience. The definition of angular acceleration is the rate of change of angular velocity or the ...
