10/16 HS physics update and homework due 10/23

Hi folks,

Today we spent a good amount of time looking at how to graph linear motion.

For homework this week I'd like you to take a look at the following websites and have some fun with the interactives.  This seems to work better on some browsers than others.  I've had luck doing these with Firefox but hopefully you won't have any problems.

For this link, get at least 8 stars.  These take some time to get used to but with some trial and error you should be able to get the hang of them.  I found the Speed v. Time Graphs to be a bit easier than the Distance vs. Time ones. When you are done take a picture or a screen shot to show me that you've done the assignment.   Graphs and Ramps Interactive

For this link, do all the "Apprentice Level" and all the "Master Level" problems.  Again, take a screen shot or a picture when you're done.  That Motion Concept Builder

Also show me graphs of the following scenarios.  I'm looking for slopes here not numbers so no calculations necessary.  However, if you're not sure what it may look like feel free to add numbers if you need.  Be sure to be very comfortable with these.  You can bet some kind of version of these will be on an upcoming quiz.  I've included answers so you can check yourself and make sure you're ready for the quiz.

1.  Show me a velocity vs. time graph of a ball rolling down a hill at a constant acceleration.

2.   Show me a position vs. time graph of a ball rolling down a hill at a constant acceleration.

3.    Show me an acceleration vs. time graph of a ball rolling down a hill at a constant acceleration.

4.  Show me a velocity vs. time graph of a car coming to a stop at a stop light.  Assume constant acceleration.

5. Show me a position vs. time graph of a car coming to a stop at a stop light.  Assume constant acceleration.

6. Show me an acceleration vs. time graph of a car coming to a stop at a stop light. Assume constant acceleration.

Have fun!

Best,

Jim Mueller
