It is a vector quantity equal to the force applied to an object times the duration the force was applied. It is usually represented by the symbol 'J'.

  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:
