What is impulse

In classical mechanics, impulse is the integral of a force, F, over the time interval, t, for which it acts. Since force is a vector quantity, impulse is also a vector quantity. Impulse applied to an object produces an equivalent vector change in its linear momentum, also in the resultant direction.

the electric field is a “force field” around a charged object that illustrates the direction the electric force would push an imaginary
