Ex: 7.P.002 A bicycle wheel has a radius of 0.347 m. How far (path length) does a point on the circumference travel if the wheel is rotated through angles of 30°, 30 rad, and 30 rev, respectively? How many revolutions is 30 radians?

Rigid Body ! Every point on the object undergoes circular motion about the point O ! All parts of the object of the body rotate through the same angle during the same time ! The object is considered to be a rigid body ! This means that each part of the body is fixed in position relative to all other parts of the body
