Some articles on mass, pendulum:
... Moment of inertia can be obtained by considering the movement of a mass at the end of a lightweight rod forming a simple pendulum, which can be studied using Newton's second law of motion ... The weight of the mass is a force that accelerates it around the pivot point ... This weight also generates a torque T on the pendulum around the pivot point and the acceleration of the mass a = rα is defined by the angular ...
