I've always heard that science can't answer the 'why' questions, but
I've also been really hazy on just what differentiates "why" from
"how" and the like. I've only really seen it as a tautology: If
science can't answer a question like that, we call it "why"; if
science CAN, then we call it a "how". Probably I need to take some
philosophy classes, but they've always struck me as questionable
logic and an almost fanatical refusal to anchor their premises to
the real world.
What IS the difference between "how" and "why"?
I would not say "f causes ma". To me, that sounds like saying "1+1
causes 2".
But I know I do say things like: "An unbalanced force causes an
object to accelerate."
Or sometimes I ask my students to compare a diver standing on a
platform with a diver in mid-air and I ask "Why is this one
accelerating and that one not?" The answer I am hoping for is
"because one is experiencing forces that balance and the other is
not. The unbalanced forces cause acceleration."
Is this all wrong? Should these questions not be asked? Or should
the answer be "physics doesn't explain why"?
But I know I do say things like: "An unbalanced force causes an
object to accelerate."
