This article is about the physical quantity impulse. The term impulse can also refer to any short-duration signal such as a nerve impulse, the comic book character (and comic book) Impulse, or a notional signal used to calculate impulse response, in the continuous case the Dirac delta function.

In classical mechanics, an impulse changes the momentum of an object, and has the same units and dimensions as momentum. The SI unit of impulse is the same as for Momentum, and is kilogram metre per second (kg m /s ). An impulse is calculated as the integral of force with respect to duration.

where

I is the impulse, measured in kilogram metre per second

F is the force, measured in newtons

t is the time duration, measured in seconds

Using the definition of force yields:

Impulse driveIn Star Trek, the impulse drive is the sub-light speed engine that the starships use when they are not travelling at warp speed or in hyperspace. It allows ships to travel non-stellar distances fairly quickly. For example, Starfleet Academy cadets use it	Impulse TrackerImpulse Tracker is a multi-track digital sound sequencer which proliferated on the DOS platform. It was authored by Jeffrey Lim and discontinued after version 2.

In control theory the impulse response is the response of a system to a Dirac delta input.
