Mashindano ya gari imeongezeka kwa umaarufu katika miaka ya hivi karibuni. Kama kila gari linakwenda kwenye njia iliyopigwa karibu na upande, magurudumu yake pia huzunguka haraka. Magurudumu hukamilisha mapinduzi mengi ilhali gari hufanya sehemu moja tu (arc mviringo). Tunawezaje kuelezea kasi, kasi, na vikosi vinavyohusika? Nguvu gani inaweka racecar kutoka kugeuka nje, kupiga ukuta unaopakana na kufuatilia? Nini hutoa nguvu hii? Kwa nini wimbo banked? Tunajibu maswali haya yote katika sura hii tunapopanua kuzingatia sheria za Newton za mwendo.
