You stick a paper onto a fridge with a magnet. There are two free body diagrams, one for the paper and one for the magnet. What are the forces acting on each object, which way do they point?
paper: force pushing in from magnet, force of ref pushing back, gravity, and friction point up. Friction=gravity
magnet= gravity down, friction up, horizonal force of attraction to referig.
