How do I find magnitude and direction of net impulse? I think I found change of momentum. Is it the same?

Question

anonymous · Answer

Yep, it's the same. The change is momentum is define so that:

$\ \Delta tF_{net} = \Delta p$

The left-hand side is impulse. The direction of the impulse is the same to that of the$\ F_{net}$.

So what's the difference between net impulse and impulse?

anonymous · Answer

It is referred as just impulse. The impulse is the net force applied during a time t.

The longer is the time that the force is applied to a system, the greater is the change in momentum it experiences. In situation where the mass doesn't change, the only change experienced by the system (the object) is in velocity.
