Assume that if B were slightly larger than C is to be interpreted as if mass of B is slightly larger than that of C² ) Descartes’ Laws of Collision m B = m C and u B = u C : First , if these two bodies, for example B and C, were completely equal in size and were moving at equal speeds, B from right to left, and C toward B in a straight line from left to right; when they collided, they would spring back and subsequently continue to move, B toward the right and C toward the left, without having lost any of their speed. For, in this case, there is no cause which could take their speed from them, but there is a very obvious one which must force them to spring back; and because it would be equal in each, they would both spring back in the same way. m
