vc at D, whenit will be evident, from the geometry of the figure, that vc passes;through the centre C of the circle ; this fact is independent of thelength of the arc P^, and leads us to assert that the resultant accelera-tion of the point is directed constantly towards the centre of the circle. In… … E F (a) (b) FIG. 48.—Motion in a circle. (c) in velocity becomes OAB (Fig. 48, c), in which OA and OB are each Imade equal to v and AB represents the change in velocity. Repe-tition of the construction for successive small arcs taken completelyround the circle in Fig. 48 (a) will give a polygon…
