Combined Motion

of Rotation and

Translation

22.1.INTRODUCTION

We have already discussed in chapter 17 linear

motion or motion of translation. And we have also

discussed in the last chapter motion of rotation. But

sometimes a body has, simultaneously, a motion of

rotation as well as translation such as wheel of a car, a

sphere rolling (without slipping) on the ground etc. A

little consideration will show, that such a motion will

have the combined effect of rotation as well as

translation. Now in this chapter, we shall discuss the

combined motion of rotation and translation.
