Objective: Confirm Newton’s equation of motion
For a body that rotates about a fixed axis with uniform acceleration, the angle of rotation φ increases in proportion to the square of the time t. From this proportionality factor it is possible to calculate the angular acceleration α, which in turn depends, according to Newton’s equation of motion, on the accelerating torque (turning moment) and the moment of inertia of the rigid body.
