impulses
In physics, impulse is the change in momentum produced by a force acting over a time interval. It is the integral of force with respect to time, J = ∫ F dt. The impulse-momentum theorem states Δp = J, meaning momentum changes by the amount of impulse. Impulse depends on both force magnitude and duration; a sharp, brief push can equal a longer, weaker one. Units are newton-seconds (N·s). Impulses are central to explanations of collisions, recoils, and propulsion.
In signal processing, an impulse (Dirac delta) is an idealized, instantaneous input used to probe systems. The
In neuroscience, a nerve impulse or action potential is a rapid, transient rise and fall in membrane
In psychology, impulsivity refers to acting with limited forethought or consideration of consequences. It is a
