Question

What are some examples of impulse?

Answer 1

Impulse `vec(I)` is a vector quantity that describes the effect of a fast varying force applied to an object for a short time:
The effect of an impulse on an object is a variation of its momentum `vec(p)=mvec(v)`:

`vec(I)=Deltavec(p)`

Every time you have a quick, rapid, fast interaction between objects you have impulse as in the following examples:
