When Arnold gets ahold of a Railgun
Later in the movie Arnold gets ahold with not 1, but 2 Railguns in which he then uses to destroy all the bad guys by dual wielding. When the first two bad guys show up he starts rapidly firing the Railguns towards them. In the scene there is absolutely no recoil and when the bad guys get hit they fly back as if the shot caught them. This could be the longest dissection of this scene alone on how inaccurate this is. First of all the if this force is brought upon the bad guys the same would be into Arnold's shoulder. This is basic law of conservation of energy. Whatever energy that is placed on the subject should also happen to the person firing the weapon. That's why you don't see a .50 caliber rifle being carried around like it's a nerf gun. It would be very difficult to harness this type of force. Especially since it's traveling almost the speed of light. Secondly this "force"/"rail" being fired at the bad guys would probably not move them much at all. It would be so quick that it would go straight through their body. A normal assault rifle used in combat today fires a small bullet at 2970 m/s and rarely is the bullet left in the body. There is almost always an entry and exit wound. The fact that this Railgun is shooting hundreds and hundreds of times faster and launches the bad guys at basically the same speed is almost cartoonish. But Hey, it's Arnold, its okay.
There are many more scenes that could go into extreme detail on the falseness of this movie's physics such as the airplane scene, let's not forget the alligator scene, and many, many more that are some of the worst I've seen.
Be careful. It's the conservation of momentum that applies mostly in this case. Not the conservation of energy. They are not the same thing, and it's important for you, as a student of (movie) physics, to be able to distinguish them.
