I think you’ll like using the work-energy theorem, it’ll save you some time and a couple of steps. Don’t forget about friction!

Work, I mean? Great intro to chapter 5! Josh, I think you almost did move the lab station! :) I think you’ll all do great with the work problems, just remember everything from the last chapter and multiply by d!

Good luck in studying for your test. Practice, practice practice the problems, but don’t forget the conceptual stuff. If you get a chance, watch the Julius Sumner Miller videos on Newton’s laws in the Vodpod below, or look them up on You Tube. I think they’ll help a lot with the conceptual information. Help session in the morning at 7:15 A.M., if you need extra help. I’ll be praying for you!

So why don’t things that are moving just keep moving? Here’s the lecture from today 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 and ONLY if your object is moving at a constant velocity, Ff will equal Fa. Fn is only sometimes equal to Fw. If your object is pulled at any angle (or pushed), Fn will be a part of Fnet in the vertical direction. Is that enough for now? Have a great weekend!
