AngularAcceleration Formula. Angular velocity is the rate of change of angular position of a rotating body and it is represented as follows: ω = θ t. Where, ω = Angular Velocity. θ = Angle Rotated. t = Time Taken. ... When the angular velocity is constant , the angularacceleration is 0. bsar opportunity 9114; drag x jordan; costa mesa car. . Suppose the angular velocity of the wheel is [omega]. The corresponding linear velocity of any point on the rim of the wheel is given by ... Thus, the yo-yo rolls down the string with a constantacceleration. The acceleration can be made smaller by increasing the rotational inertia and by decreasing the radius of the axle. 12.3. Torque. Figure.
