Problem
Answer the following with reference to the rotational motion of a rigid body about a fixed axis when the angular acceleration is constant.
(i) State the mathematical relation connecting angular displacement θ, initial angular velocity ω0, angular acceleration α and time t for such motion.
(ii) Using this relation, explain qualitatively how the angular displacement varies with time. What is the nature of the θ–t curve?
(iii) Draw the θ–t graph for this case. Mark clearly the initial angle, the intercepts and indicate whether the curve is linear or non-linear.
