 +===== Equations of motion for rotational motion =====
 +At the beginning of the course we derived, using calculus, a set of equations for motion under constant acceleration.
 +$v= v_{0}+at$ ​
 +$x= x_{0}+v_{0}t+\frac{1}{2}at^2$
 +We can equally derive similar equations for our rotational quantities. Indeed as we can see that the relationships between the new rotational quantities we have now are exactly the same as those between the translational quantities we can simply rewrite the translational motion equations in terms of rotational variables.
 +$\omega= \omega_{0}+\alpha t$ 
 +$\theta= \theta_{0}+\omega_{0}t+\frac{1}{2}\alpha t^2$
