Etymology: [See Impel.]
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:
Chambers 20th Century Dictionary

Impuls′ive, having the power of impelling: actuated by mental impulse: (mech.) acting by impulse: not continuous.—adv. Impuls′ively.—n. Impuls′iveness. [L. impulsus, pressure—impellĕre.]
The Standard Electrical Dictionary
(a) An electro-magnetic impulse is the impulse produced upon the luminiferous ether by an oscillatory discharge or other varying type of current; the impulse is supposed to be identical, except as regards wave-length, with a light wave. (b) An electro-motive impulse is the electro-motive force which rises so high as to produce an impulsive or oscillatory discharge, such as that of a Leyden jar.
Military Dictionary and Gazetteer
The act of impelling, or driving onward with sudden force; impulsion; the action of a force so as to produce motion suddenly, or without appreciable loss of time. Also sudden motion exciting to action; hasty inclination; influence acting unexpectedly, or with momentary force; impression; instigation; as, the troops moved forward with one impulse.
