angular velocity - mrsk.ca
22 Angular Speed Definition If P is a point moving with uniform circular motion on a circle of radius r, and the line from the center of the circle through P sweeps out a central angle in an amount of time t, then the angular velocity, (omega), of P is given by the formula t n s Example A point on a circle rotates through 3 4 radians in 3 sec. Give the angular velocity of the point.
