1. The problem statement, all variables and given/known data 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 Weights 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). 2. Relevant equations 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. 3. 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... PLEASE HELP!
