1. The problem statement, all variables and given/known data
Well pretty much i am just starting on my concept quilt and my teacher gave us 9 types of forces that we learn well studied and i need help to understand what she wants me to do.

these are the types:
Coefficient of Friction
contact f
Field F
Force Diagram
Kinetic Friction
Net external force
normal F
static friction
weight

2. Relevant equations

am i suppose to do only formulas? like "net external force F-ma" or ma i suppose to give an example?

what is contact F and Field F and Normal F?

Can anybodi give me examples i'll be realli grateful!

3. The attempt at a solution

i attempt to try to find examples yet it didn't work so i landed upon here :D

Hard to say what your teacher wants, but I'd provide a formula that has that force and write a sentence describing each. Normal force refers to the force that objects apply as a reaction to some external force (i.e. the floor applies a normal force to me as a result of my weight). I'd also relate normal force to how it affects friction force. Field force may be related to magnetic and electric fields? Contact force is probably more obvious than you think.
