Physics 11-25-13 Number 22 and Answers

PHYSICS – Great work on the problems today! Are you still trying to follow formulas, or are you starting to be able to think through the problems and and begin to make connections?

Be careful – don’t just start grabbing formulas and throwing in numbers. Make sure the formulas make sense – ask yourself every time why it makes sense for you to put that particular number in that particular part of the formula. And work them over and over and over until it comes naturally to you!

Homework tonight is changed a bit: Pg. 179 – 184: 46 – 49, 51 like it says, and then 50 and 52 if answered will count as a bonus homework that will take the place of one other unfortunate homework grade. Answers to all of these are on the vodcast – at the end, I think.

Speaking of making connections – let’s do that tomorrow! If you were to design a roller coaster, what would it look like?!? Don’t forget to print & read the Roller Coaster Lab and bring your design tomorrow to class.
