1. Momentum

   In classical mechanics, linear momentum or translational momentum is the product of the mass and velocity of an object. For example, a heavy truck moving fast has a large momentum—it takes a large and prolonged force to get the truck up to this speed, and it takes a large and prolonged force to bring it to a stop afterwards. If the truck were lighter, or moving more slowly, then it would have less momentum. Like velocity, linear momentum is a vector quantity, possessing a direction as well as a magnitude: Linear momentum is also a conserved quantity, meaning that if a closed system is not affected by external forces, its total linear momentum cannot change. In classical mechanics, conservation of linear momentum is implied by Newton's laws; but it also holds in special relativity and, with appropriate definitions, a linear momentum conservation law holds in electrodynamics, quantum mechanics, quantum field theory, and general relativity.

Examples of momentum in a Sentence

1. Ted Cruz:

   This fevered pipe dream of Washington that at the convention they would parachute in some white knight who will save the Washington establishment, it is nothing less than a pipe dream, it ai n’t gon na happen. If it did happen, the people would quite rightly revolt. Senator Cruz only bolstered his case that he's gaining momentum in the battle against front-runner Trump with his Wisconsin victory. He scored 48 percent of the vote to Trump's 35 percent, and picked up the lion's share of the state's delegates. Ohio Gov. John Kasich trailed far behind. The race heads next, though, to New York state where Trump has a commanding lead in the polls. The criticism of having ties to the establishment is an unusual one for Cruz -- who has portrayed himself as an outsider fighting against what he calls.
