WebJust as a net force causes acceleration, a net torque causes angular acceleration, so you can think of torque as the angular equivalent of force. Torque brings forces into the rotational world. Most objects aren’t just points or rigid masses, so if you push them, they not only move but also turn. For example, if you apply a force tangentially ... WebAngular Acceleration Examples. 1) If a rotating disc changes its angular speed at the rate of 60 rad/s for 10 seconds. Calculate its angular acceleration during this time. Solution: The change in angular velocity is 60 rad/s. The time taken for this change to occur is 10 s. Substituting the above values in the angular acceleration formula, we get: gazozaur
