The rotation angleis defined asthe ratio of the arc length to the radius of curvature:where arc lengthis distance traveled along a circular path andis the radius of curvature of thecircular path. The quantityis measured in units of radians (rad), for whichThe conversion between radians and degrees is.Angular velocityis the rate of change of an angle,where a rotationtakes place in a time. The units of angular velocity are radians per second(rad/s). Linear velocityand angular velocityare related by6.2Centripetal AccelerationCentripetal accelerationis the acceleration experienced while in uniform circular motion. It alwayspoints toward the center of rotation. It is perpendicular to the linear velocityand has the magnitude
