Guess what I found – an old, old review of a few of the harder/different conversion factor problems and a percent error problem snuck in at the end. Will it help you in working problems?

Also, don’t forget the Interactive Review Games with your online text and also sciencegeek.net. Good luck studying! I’ll be praying for you!!

Physics 9-7-12 Free Fall, Pt. 2 and Reaction Times

PHYISICS – Here’s a question – how could this kid figure out how tall this cliff is? Good job on finding the height of the balcony Now go forth and write it up in your lab book. And reaction time! Who’s gonna have the fastest rxn time? Post your results here!

From Friday, here’s the work we did on #32, the “ball dropped from the top of a building and thrown up from the ground at the same time” problem. The ones this weekend will be a little challenging, but after today’s hints, no problem!!

Draw a picture, write down what you know and are looking for. What formula fits? On the problems with something going up and then dropping something else, like the pelican or the parachute, don’t forget that the item dropped has the velocity of the first thing. And to find how far apart they are, you usually have to figure in that the first thing was still moving when the second thing was dropped. Make sense? And be careful to keep positive and negative straight! Good luck – you’re doing a great job with these. I’m really proud of you!! Have a great weekend!
