both cars vary in this search . moreover the intention of both drivers also differ , although this has halt relevance in science .the chemical energy in the fuel is converted to mechanical at the combustion bedroom of the carwhat is however relevant is that when one moves behi! nd a be active car there is a net force that applies . force has strenght and direction [Tilley BW] . in a situation where there is covering proximity between the two cars , the net force adds the two and the car behind is likely going to be contemptible with the summation . this is the risk and trick . so , beware !referenceTilley , BW .
