Filter forces
Posted: Fri Mar 26, 2010 4:55 pm
I'm a newb at the philosophy of physics. I have a question about what exerts force:
If you have a light filter or a strainer or anything that lets matter with certain attributes through and prevents the rest from passing, is it exerting a force on the rejected matter? If so, what kind of force?
>>Perhaps a better way to ask the question is, 'Can force be passive, and does it affect matter?'
Thanks in advance for your thoughts.
