A mental force which simply and directly urges to action; hasty inclination; sudden motive; momentary or transient influence of appetite or passion; propension; incitement; as, a man of good impulses; passion often gives a violent impulse to the will; to buy something on impulse.
Origin: [L. impulsus, fr. impellere. See Impel.]
A thrust; a push; a sudden force that impels.
A wish or urge, particularly a sudden one.
The integral of force over time.
The total impulse from the impact will depend on the kinetic energy of the bullet.
Origin: From impulsus.
the act of impelling, or driving onward with sudden force; impulsion; especially, force so communicated as to produced motion suddenly, or immediately
the effect of an impelling force; motion produced by a sudden or momentary force
the action of a force during a very small interval of time; the effect of such action; as, the impulse of a sudden blow upon a hard elastic body
a mental force which simply and directly urges to action; hasty inclination; sudden motive; momentary or transient influence of appetite or passion; propension; incitement; as, a man of good impulses; passion often gives a violent impulse to the will
to impel; to incite
Origin: [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
im′puls, n. the act of impelling: effect of an impelling force: force suddenly communicated: influence on the mind.—n. Impul′sion, impelling force: instigation.—adj. 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.
