For Monday, Sept. 24

Happy Monday, everyone! 

Periods 3-4, 8-9

Reach consensus on answers and thought process for HW sets - we've got plenty of white boards, just need a few volunteers to show us what you did and talk it through.

After that, try the Barrons review set in the Electrostatics folder on Doc V's school web site. Solutions are in there if you scroll down. In the folder is also a file with video links relevant to electrostatics, in case you need to check on anything. Also plenty of worked examples in Chapters 21-23. Anything related to point charges and thin shells with Gauss's law is fair game on Tuesday.

If you want to meet the Dean of Engineering at Penn State, and a former Chem/Phys student, Dr. Justin Schwartz, stop in at 7:45 am Tuesday!! 

Period 5

With your Chromebooks, go to a site with links to ActivPhysics computer simulations. Click on Newton's laws. Under Describing Motion, open up simulation 1.2, Analyzing motion using graphs. Follow along with the instructions, and keep track of things and take notes in your notebook. It will ask you to open up a simulation and run it, and see what a position vs time graph looks like for the motion of a car. Start making the connection between a motion and the corresponding motion graph. As you go along, they will add a graph for velocity vs time, and finally acceleration vs time. You will be using these as a model/example to then try simulation 1.3, Predicting motion from graphs.

In 1.3, again, follow along. It will have you run an initial simulation, which shows nothing but the position vs time graph for some car motion. You will need to predict, based on what you learned and saw in simulation 1.2, what the motion of the car is, as well as what the velocity and acceleration graphs look like. Sketch out what you think the graphs should look like!
Then, open the second simulation of the problem and run it. This will show everything, and you can check to see if you are correct with the motion as well as the graphs! If you are incorrect, draw the graphs and motion that are shown, near your predictions. We can go through these Tuesday to see if we can make corrections in your thinking, if necessary.

Talk these through with a partner if you wish. The goal is to make connection between real motions and how these motion quantities are related to the motions.

If anyone is interested in engineering, please feel free to come in at 7:45 am Tuesday morning to meet a former student, who is Dean of Engineering at Penn State University! Should be interesting!
