# Difference between impulse and magnitude of force

we learned about the impulse of a force , but just then a question came to my mind , whats the difference between the magnitude of a force and its impulse , or are they the same ... ??

The magnitude of a (vector) force ##\vec F## is ##|\vec F| = \sqrt{F_x^2 + F_y^2 + F_z^2}##. The impulse of the force when it acts for time ##\Delta t## is ##\vec F \Delta t##.

thanks !! :)
