Impulse

:This article is about the physical quantity of impulse. For other meanings of the term "impulse" please see Impulse (disambiguation)

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 metres per second (kg m /s ). An impulse is calculated as the integral of force with respect to time.

~ ~ ~ ~ ~ ~ ~ ~ ~ ~

:mathbf{I} = int mathbf{F}, dt

~ ~ ~ ~ ~ ~ ~ ~ ~ ~

where

~ ~ ~ ~ ~ ~ ~ ~ ~ ~

:I is the impulse, measured in kilogram metres per second

~ ~ ~ ~ ~ ~ ~ ~ ~ ~

:F is the force, measured in newtons

~ ~ ~ ~ ~ ~ ~ ~ ~ ~

:t is the time duration, measured in seconds

~ ~ ~ ~ ~ ~ ~ ~ ~ ~

In the presence of a constant force, impulse is often written using the formula

~ ~ ~ ~ ~ ~ ~ ~ ~ ~

:mathbf{I} = mathbf{F}Delta t

~ ~ ~ ~ ~ ~ ~ ~ ~ ~

where

~ ~ ~ ~ ~ ~ ~ ~ ~ ~

:Delta t is the time interval over which the force (F) is applied.

~ ~ ~ ~ ~ ~ ~ ~ ~ ~

Using the definition of force yields:

~ ~ ~ ~ ~ ~ ~ ~ ~ ~

:mathbf{I} = int rac{dmathbf{p}}{dt}, dt

~ ~ ~ ~ ~ ~ ~ ~ ~ ~

:mathbf{I} = int dmathbf{p}

~ ~ ~ ~ ~ ~ ~ ~ ~ ~

:mathbf{I} = Delta mathbf{p}

~ ~ ~ ~ ~ ~ ~ ~ ~ ~

It is therefore common to define impulse as a change in momentum.

Classical mechanics: In physics, classical mechanics is one of the two major sub-fields of study in the science of mechanics, which is concerned with the motions of bodies, and the forces that cause them. The other sub-field is quantum mechanics. Roughly speaking, classical mechanics was developed in the 400 years since...

Momentum: In physics, momentum is a physical quantity related to the velocity and mass of an object....

SI: The International System of Units (abbreviated SI from the French phrase, Syst?me International d'Unit?s) is the most widely used system of units. It is the most common system for everyday commerce in the world, and is almost universally used in the realm of science....
