Conservation of Momentum
In the absence of external forces the total momentum of a system is always conserved
Impulse
The change in Momentum for a single object
ΔP = Pf - Pi
&
ΔP = FΔt
&
ΔP = mΔv
- The unis are eithor Ns or kgms-1 , this is the same unit and the one that is used depends on the context
- Impulse on one object is always equal and opposite to the impulse on the other onject - Newton's Third Law
