Six Stones? More Like Three Laws
This was my first time seeing Avengers: Infinity War, which was a long time coming, but I must say, I was pretty blown away. The developmental and action aspects of the movie were phenomenal like most other Marvel movies, so I wasn't close to disappointed. However, looking at a movie like this from a physics standpoint kind of messes with the magic of superheroes, but it must be done. There were many instances where one of Newton's three laws were broken by a certain character or characters. Even my roommate who was watching along with me who is in a no way an expert physicist agreed that something was not right in multiple scenes.
Newton's First Law:
The 1st law states that an object in motion will stay in motion (in a straight line) or an object at rest will stay at rest unless acted upon by an outside net force. In one of the first battle scenes between Thanos's team and the avengers, there is an example of this law being broken. Cull Obsidian, an enormous machine of an alien thing, launches a big arm claw type weapon at Iron Man as he is flying at him, quickly reversing his velocity and causing him to move with the arm. Iron Man and the arm have enough momentum to smash through both sides of a building but as soon as Stark is let go, he is stopped by a tree. If the rocket launched arm was just a constant flying object, then it and Iron man should have been stopped by the building, not a tree at the end. This defies the conservation of momentum as well.
Newton's Second Law:
Newton's Third Law:
Last but not least, the third law says that for every action there is an equal and opposite reaction. So if a force as applied to another object, that object will push back with just as much force. This law is completely shattered when Bruce Banner otherwise known as Hulk come hurtling towards Earth after his confrontation with Thanos, and lands in Dr. Strange's main lobby. He smashes through the stairs leaving a nice hole in them. Though if this law were to be complied with, there would have been a significantly larger dent, since the Earth would have pushed back with just as much force as Hulk exerted. After flying through space at such high speeds, there's no way Bruce would have just left a reasonably expensive repair to be made to the stairs.

This law basically just states that the net force is equal to the mass of the object inversely proportional to its acceleration. As an equation, this would look like ΣF=ma. Thor, the god of thunder, arrives in Wakanda after finally wielding his oh so powerful ax to save the day. He throws his ax like a boomerang, wiping out hundreds of enemy aliens, considering this ax is possibly a little heavier than most axes, but not unbearable, Thor had to have put quite a large acceleration on it for it to have the force to cause the damage it did. But when it gets back to Thor, he catches it like it's nothing and he doesn't even step back to slow it down. Obviously, he has super-strength but this is still not accurate.

OK, I was looking for very specific examples of violations of Newton's laws. Some of your examples had more to do with conservation of momentum and other concepts. I would have liked to see you really demonstrate that you understood how one or more of Newton's laws were broken. For instance, your Thor hammer example is a good one, except the way the scene violates Newton's 2nd Law is that the hammer appears to change direction without any apparent force acting on it.
