both cars vary in this flirt . moreover the intention of both drivers also differ , although this has chasten relevance in science .the chemical energy in the fuel is converted to mechanical at the combustion sleeping accommodation of the ca rwhat is however relevant is that when one m! oves behind a trigger off car there is a net force that applies . force has strenght and direction [Tilley BW] . in a situation where there is terminate proximity between the two cars , the net force adds the two and the car behind is likely going to be lamentable with the summation . this is the risk and trick . so , beware !referenceTilley , BW .
