Think you're mixing up dispersion with displacement! As dispersion is to do with waves, most commonly used for describing the effect that happens when light is shone through a prism, which results in the light being separated into the different colours.
Displacements is to do with the volume of something whether it be gas or liquid (can't remember if it's to do with with solids as solids generally stay, well, solid). So the law is that the exact same amount must exist so like in the bath you go in an the water goes up, it's being displaced.
Sorry i'm not a physicist so my explanations is what i can remember from my As physics (which is not a lot)
Its a matter of being scientifically rigorous. You can not claim the 2nd law as a law unless you first establish the first law.
no
newtons 2nd law states that if a force is put on an object then the object will move in the oppisite direction of the force no thats the third law
yes. newtons 3rd law is: "FOR EVERY ACTION THERE IS AN EQUAL AND OPPOSITE REACTION"
Gravity
It states newtons law of gravitation

no
the law of inertia
Coulomb's Law
Law of inertia.

newtons third law of motion
yes. newtons 3rd law is: "FOR EVERY ACTION THERE IS AN EQUAL AND OPPOSITE REACTION"
Newton's third law of motion is that for every action there is an equal and opposite reaction. This law is also called reciprocal motion/force or "action-reaction."
