Document Summary
Di erence between the initial and nal positions of a rotating object. Change in theta = theta nal - theta initial. The time rate change of angular displacement. Omega = change in angular position / change in time. If the initial angle of the segment is 34 degrees at a time of 1. 23 seconds and the segment moves to an angle of 62 degrees at a time of 1. 3 seconds, what is the angular velocity. W (omega) = theta nal - theta initial / t (time) nal - t (time) initial. 1 degrees/second = 0. 01745 radians / second. Angular acceleration = change in angular velocity / change in time. A = (omega nal - omega initial) / (time nal - time initial) A = change in w / change in t. Absolute angle (position) > angular displacement > angular velocity > acceleration.
