se it had someother direction, F, as in Fig. 18,then this force could be separatedinto a central component, Fc, and atangential component, FT. Nov/the effect of the latter would be to increase the speed, whichis contrary to the definition; therefore, there is no tan-gential component, and the force… … Fig. 18. UNIFORM CIRCULAR MOTION. 33 as the other, then, the speed being the same on both circles,in the same time the particle would describe equal arcs, ABand AB (Fig. 19), but the change of direction, a, in goingfrom A to B would be Atwice that in going fromA to B, or 2a.
