What is the difference between physical impossibility and logical possibility?
If you violate logical possibility, it will be neither physically possible nor metaphysically possible. Something is physically impossible (AKA nomological impossibility) if it is inconsistent or contradictory to the physical laws of nature. So something can be logically possible but not physically possible.
What is metaphysically possible?
Nomological possibility is possibility according to the laws of this world, i.e. a thing is nomologically possible if it doesn’t contradict the laws of physics, chemistry, etc. So something could be metaphysically—but not nomologically—possible if it could be the case in some world or other.
