a rapid desire or urge that encourages an unpremeditated work or sensation; an abrupt inclination: had an impulse to hightail it; an impulse of regret that made myself hesitate; bought a hat on impulse.
A motivating force or propensity: "Respect for the liberty of other individuals isn't an all-natural impulse in most men” ( Bertrand Russell).
Electronics A surge of electric power in one direction.
Physics this product obtained by multiplying the common value of a force once during which it acts. The impulse equals the alteration in energy from the force inside time interval.
Physiology The electrochemical transmission of a signal along a nerve fibre that produces an excitatory or inhibitory response at a target tissue, such as for example a muscle or another neurological.
A thrust; a push; a sudden power that impels.
A wish or desire, specially a sudden one prompting action.
The integral of force in the long run.
The work of impelling, or operating onward with abrupt power; impulsion; particularly, power therefore communicated as to produced motion all of a sudden, or immediately.
the consequence of an impelling force; motion from a-sudden or temporary force.
The activity of a force during a rather little interval period; the effect of these activity.
A mental force which merely and directly urges to activity; hasty inclination; abrupt motive; temporary or transient impact of desire for food or enthusiasm; propension; incitement
energy communicated suddenly; the result of an impelling power; a thrust; a push.
Especially In mech.: An infinite force or activity suffering for an infinitely limited time, to be able to produce a finite momentum.
The resultant of all such forces functioning on a body at any immediate, fixed into a couple of and a force across the axis of that couple.
The energy generated by a force in any time.
A stimulation regarding the mind to action; the impelling force of desire for food, desire, aversion, or any other emotion; especially, a sudden personality to do some act that will be maybe not caused by representation; abrupt determination.
Any interaction of force; any compelling action; instigation.
A mental impression; a concept.
the electric release that moves along a nerve fiber
an impelling power or strength
an instinctive motive
(electronics) a sharp transient wave inside regular electric condition (or a few such transients)
