PHYSICS: Who knew snow skiing could be so complicated! Well friction problems on an incline anyway. Here’s the lecture/problem review from Monday on friction problems on an incline. Remember, drawing the diagram is super, super important. Label all the forces, and apply the concepts you know about net forces and resultant forces. And practice!! flickr [...]

PHYSICS: So why don’t things that are moving just keep moving? Here’s the intro lecture on friction. Remember a few key things. Net forces produce acceleration. You can find Ff a couple of different ways – it’ll be part of a net force equation and can be found from the coefficient of friction equation. If [...]
