Passage - I : Angular speed omega is the rate which an object rotates Although usually measured in radians per second, omega can also be expressed in degrees per second. For instance, consider a merry - go - round. Figure shows its angular speed as a function of time t. In this graph, a positive value of omega indicates counterclockwise rotation. A ''complete revolution'' occurs when the merry-go-round turns through one full circle Between t=30s and t=40 s, the merry-go-round
