## Summary

Momentum…is a amount that defines an object"s resistance to protecting against (a type of "moving inertia").is represented by the symbol p (boldface).is the product of one object"s mass and velocity.

p=mv

is a vector amount (since velocity is a vector and mass is a scalar).Impulse…is a amount that describes the impact of a net force acting on an item (a type of "moving force").is stood for by the price J (boldface).is the product of the mean net pressure acting on an object and that duration.

You are watching: What is the unit for impulse

J=F∆t

is the force-time integral.
 J= ⌠⌡ Fdt
is a vector quantity (since pressure is a vector and also time is a scalar).Impulse-Momentum TheoremThe impulse-momentum theorem claims that the adjust in inert of things equals the impulse used to it.

J=∆p

If massive is constant, then…

F∆t=m∆v

If mass is changing, then…

Fdt=mdv+vdm

UnitsThe SI unit of impulse is the newton second.The SI unit of momentum is the kilogram meter every second.These systems of impulse and also momentum space equivalent.

Specific impulseis a measure up of the efficacy the rocket propellants.if identified as impulse per mass (or thrust per mass circulation rate)is equal to exhaust velocity and also has the SI unit the meter per second.
 Jsp= J = T =v m qm
if characterized as impulse per weight (or thrust every weight flow rate)is same to exhaust velocity separated by acceleration due to gravity and has the SI unit of second.
