23.1.INTRODUCTION

In the previous chapters, we have discussed the

motion of particles or bodies in a straight line or in

rotation. But in this chapter, we shall discuss the

motion of a particle or point along a circular path and

its effect on one of its diameters.

Consider a particle starting from x and moving

round the circumference of circle in an anti-clockwise

direction, with a constant angular velocity, as shown

in Fig. 23.1. Let P be the position of the particle at

any instant and N be the projection of P on the diameter

Y-Y' of the circle.
