Freebase

  1. Impulse

    In classical mechanics, impulse is defined as the integral of a force with respect to time, which gives you the change in the momentum of the body being acted on by the force. A force causes acceleration, a change in the velocity of the body, for as long as it acts. A force applied over a long time therefore produces a bigger change in momentum than the same force applied briefly: the change in momentum is equal to the product of force and time. Conversely, a small force applied for a long time can produce the same change in momentum - the same impulse - as a large force applied briefly. The SI unit of impulse is the newton second; the quantity of impulse is force × time interval, or in shorthand notation:
