impulse
  تکانه   
tekâné (#)

Fr.: impulsion   

Of a force acting on a body, the → product of the → force and the → time for which it acts. If the force changes with time, the impulse is the → integral of the force with respect to the time during which the force acts, and is equal to the total change of → momentum produced by the force: ∫F dt = ∫m dv. Impulse is a → vector quantity.

From L. impulsus "a push against, pressure, shock," p.p. of impellere "to push, strike against, drive forward," from → in- "into" + pellere "to push, drive."

Tekâné, from tekân "involuntary motion, sudden shaking," related to tak "rush, quick motion, stroke, blow" (tâxtan, tâzidan "to run; to hasten; to assault"); Mid.Pers. tak "assault, attack;" Av. taka- "leap, run," from tak- "to run, flow;" cf.

impulse; → momentum; → principle.
