impulse, in mechanics: see momentum momentum (mōmĕn`təm) ..... Click the link for more information. . Impulse (mechanics) The integral of a force over an interval of time. For a force F , the impulse J over the interval from t0 to t1 can be written as Eq. (1). (1) The impulse thus represents the product of the time interval and the average force acting during the interval. Impulse is a vector quantity with the units of momentum.  The momentum-impulse relation states that the change in momentum of a mass m over a given time interval equals the impulse of the resultant force acting during that interval. The momentum change can be expressed in terms of the velocities v 1 and v 0 at times t1 and t0, respectively, giving Eq. (2). (2) |
