Hello,(adsbygoogle = window.adsbygoogle || []).push({});

I am having some trouble understanding this whole concept about friction as well as force (Newton's 2nd law). What I was told is that Fnet=Ma, which I'm guessing stands for sum force = mass * acceleration.

What I wasn't told is how the units are dealt with. I am very used to dimensional analysis, and that isn't helping me one bit. What exactly do these units need to be? I was thinking:

F=N

M=kg

a=m/s^2

As for friction, I'm not even sure where to begin with that. I don't think that I was given any specific formula.

Thanks,
