1. Momentum(n.)

   A property of an activity or course of events, viewed as analogous to forward motion or to physical momentum (def. 1), such that the activity is believed to be able to continue moving forward without further application of force or effort; -- often used to describe an increase in the acquisition of public support for a purpose; as, as, the petition drive gained momentum when it was mentioned in the newspapers.

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

5. Jason Furman:

   The problem with the economic side is that if it lasts more than a few months, it then takes on its own momentum, if you look across the United States and across other countries, the unemployment rate can go up very quickly, but it cant come back down very quickly. It never has. A business whose balance sheet is in tatters after nine months without revenues might go bankrupt, it might go out of business, or it wont be in position to hire people back immediately even if demand returns.
