If an object falls there are two ways to consider momentum conservation
Way 1:
The system involves just the object therefore the gravitational force is an EXTERNAL force so momentum is NOT conserved
Way 2:
The system involves object and earth. The increase in momentum of the object down = increase in momentum of Earth up (therefore momentum is conserved)
Is this correct?
