I think we have been in this point before. What you mean with being realists?
First, if I keep using a term like that and you don't know what it refers to, don't wait until we've gone back and forth umpteen times before finally pointing out that you don't even know what I mean by the term.
Realism refers to the belief that the thing/phenomenon in question exists extramentally--that it's not simply a mental construct, a way to think about it.
Why do you answer my question with another question?
In this case because your comments had nothing to do with why materialists would necessarily be realists on physical laws, whereas that's what I'm focusing on. So I'm asking you to either tell me what, in your mind, your response has to do with the logical connection between materialists and physical laws or to instead address that.
How materialism explain that matter moves?
Materialism isn't a stance on "how matter moves." If a materialist explains that, and makes a comment about physical laws while doing so, they might have any conceivable stance on "how matter moves" and what the status of physical laws are. Those stances don't affect that the materialist is a materialist. That's just the point.
Well, materialism claims that everything is made of matter.
That part is correct (well, more or less--it depends on whether you're thinking about it so that relations and processes are included).
It has to explain that how matter moves too.
This part has nothing to do with whether something counts as materialism or not though.
It's similar to this: if we were to invent a term, "Toyotaist," to denote someone who thinks that the only kinds of automobiles that should exist are Toyotas, then maybe you'd think that they should have an opinion on tire brands, too. And maybe some Toyotaists would have opinions on tire brands--some might think there should only be Hankook tires, some might think that both Hankooks and Michelins are okay, etc. But their opinions on tires would have nothing to do with whether they're Toyotaists or not. "Toyotaist," as a conventional term, is ONLY about their view of what sorts of cars should exist. There are Toyotaists who want only Hankook tires and Toyotaists who like all sorts of tires, etc.
"Materialist" works the same way with respect to opinions about (the status of) physical laws.
