The product of the mass of a body by its velocity is called its momentum, or quantity of motion. In the C. G. S. (centimeter-gram-second) system (§ 28) the unit of momentum is the bole, i.e., the momentum of 1 g. of matter moving with a velocity of 1 cm. per second. The expression is the formula for momentum b = Mv.
There is no name for the unit in the F. P. S. (foot-pound-second) system, but the unit would be practically the momentum of 1 lb. moving at the rate of 1 ft. per second. A ferryboat moving slowly has great momentum, as is shown when it strikes the side of the slip.
