Momentum:
* The linear momentum of an object is a measure of the object's "umph"

* Momentum is a vector quantity, whereas Energy is a scalar quantity. This means that the momentums of two objects have to be added vectorially in order to find the total momentum of a system consisting of the two objects.

SI Units: kg m/s = N.s

Impulse:
* The force-time "crack" applied to an object due to the action of a force for a duration of time.

SI Units: Ns = kg m/s (Same as momentum)

Impulse-Momentum Theorem:
* Any impluse acting on a system changes the system's momentum.
