Physics 9-21-16 Intro to Vectors & Relative Motion

PHYSICS: Awesome introduction to relative motion and vectors! Wow!

Here’s the a vodcast from a couple of years ago on the intro to vectors – and below that, a MOST AWESOME demonstration of the addition of two vectors with (almost) equal magnitude and opposite direction. Did you guess what the ball would do?

Chemistry 9-21-16 Graphing Exercise Recap

CHEMISTRY: How’d you do today with your Excel graph? Once you get the hang of it, I predict you are going to want to always do these kind of graphs instead of hand drawn!

HOMEWORK INFO: You must bring a printed rough draft of BOTH of your graphs to class tomorrow – Thursday. Be sure and email your Excel graph to yourself – or save it some other way so that you can access it from school in case you need to make changes!

HOMEWORK UPDATE: Double check the Exercise 1 that you did. If you did the physics Exercise 1 (graphs had questions about motion) then you can redo it if you want to – you don’t have to redo it, but it will be graded for accuracy. Here’s the link the the CORRECT Graphing Exercise 1

Speaking of which – be careful with your hand drawn graphs! Carefully review the instructions on how to draw them. Common mistakes – switching independent and dependent variables, line not a best fit curve, graph too small, forgetting to label the axis.

Super important – when you scan your hand drawn graph to insert it into your Word or Google doc, remember that you have to scan it as an JPEG image and NOT a PDF this time! If you are using an app to scan, you’ll probably need to change the settings to scan as a JPEG.
