Is there any like websites that have pretty good diagrams and explanations of how to go about Force problems. Problems containing Net forces, Friction, etc. I am just really lost because our physics teacher (who already is a bad teacher) left for 2 weeks since he had a baby right when we were about to begin a new chapter, and left us with some random sub who took a class of physics in college but doesnt really know anything. Therefore he just goes through powerpoints not explaining anything.

I figured out for the most part how to do like

Net force = Mass * Acceleration

W= Mass * gravity

i know how to do something pulled at an angle like

Fg *cos(beta)
or fg *sin(beta)

I basiclly get lost when friction is thrown into the mix ( like static and kinetic ) and objects on an incline.
