The torque T, the moment of inertia I and the angular acceleration are related by the equation: Example. A force of 5 N is applied for 3 s to the rim of stationary wheel of mass 4 kg and radius 0.5 m. Calculate: (a) the angular acceleration, (b) the final angular velocity, (c) the number of revolutions in that time,

Angular acceleration. If an object is moving in a circle at a constant speed, its direction of motion is constantly changing. This means that its linear velocity is changing and so it has a linear acceleration. The existence of an acceleration means that there must also …
