Meaning: an impelling force or strength; "the car's momentum carried it off the road"
Meaning: the product of a body's mass and its velocity; "the momentum of the particles was deduced from meteoritic velocities"
Apparently the car had struck the tie just at the moment of losing momentum.
Roar upon roar, as the infinite momentum of the disintegrating uranium struck obstacle after obstacle.
Over the ground ran the dainty, little aeroplane, until, having momentum enough, Tom tilted the wing planes and the machine sailed up into the air.
Through this shot the craft, and then, when sufficient momentum had been obtained, Tom, at a command from the aeronaut, pulled the lever of the elevation rudder.
Previous to the dumping of a skip, the rolls were speeded up to a circumferential velocity of nearly a mile a minute, thus imparting to them the terrific momentum that would break up easily in a few seconds boulders weighing five or six tons each.
The act of breaking and crushing would naturally decrease the tremendous momentum, but after the rock was reduced and the pieces had passed through, the belt would again come into play, and once more speed up the rolls for a repetition of their regular prize-fighter duty.
From a consideration of these facts, and with his usual tendency to upset traditional observances, Edison conceived the bold idea of constructing gigantic rolls which, by the force of momentum, would be capable of crushing individual rocks of vastly greater size than ever before attempted.
