So I have this lab I have to do about finding the relationship between static friction and normal force. So basically I need to find find how the Static Friction and Normal Force relate by doing a lab experiment.
The materials I have are:
Spring balance / scale
Different surfaces of textures (probably something to do with friction)
and some sort of Cube weight.
So I just don't understand how we would conduct an experiment to find the relationship between normal force (something that goes up) and static friction (Something that is at rest).
Fnet = ma
My teacher also said something about Coefficient of Friction = Static friction / Normal force but I don't see how I can apply that in this lab overall.
The Attempt at a Solution
I really am confused about what to do for this lab. I would really appreciate if you could give me guidance as to how I could approach this lab to find the relationship.
I know it has to do with something about measuring the mass of the weights in different frictions and I think calculating f=ma but am confused...
