both cars vary in this visit . moreover the intention of both drivers also differ , although this has express mail relevance in science .the chemic energy in the fuel is converted to mechanical at the combusti on chamber of the carwhat is however releva! nt is that when one moves behind a wretched car there is a crystallize force that applies . force has strenght and direction [Tilley BW] . in a situation where there is slopped proximity between the two cars , the net force adds the two and the car behind is likely freeing to be moving with the summation . this is the risk and trick . so , beware !referenceTilley , BW .
