In many cases, rolling is obtained by a speed of rotation at a point or line of contact that is normally equal to the speed of translation. In absence of sliding the motion of rolling is normally called pure rolling (Walker, 2010). This means that for a rolling object the mass centre moves by the translational motion, where as the other parts of the object, rotate around the centre mass.
