Consider a body rotating about a fixed axis. The equation of motion (rotational motion) is
I = M.I of body about axis of rotation.
\(\tau\) = Net torque of forces about axis of rotation.
α = Angular acceleration.
For a body having “uniformly accelerated” rotational motion the kinematical equations discribing motion are
where ω(0) and ω(t) denote initial (i.e. t = 0) and instantaneous (i.e. t = t) angular speed of body. α is the uniform angular acceleration and θ is angle described in time t = t.
