This sheet will provide you with a quick reference. Refer to it if you are struggling or forget the definition of something. (0 points)
Lab Activities:
Pulling on Spring Scales and Force Sensors (10 points)
1. Take two spring scales. Connect them and pull. What do you notice?
2. Take two electronic force sensors. Connect them and pull while collecting data to make a graph. What do you notice?
3. Call me over and show/explain to me how what you observed demonstrates Newton's Third Law.
Concept Questions:
Figure out the answers to these questions. When you understand the answers to these questions call me over and I will ask you questions to verify that you understand. (10 points)
Webassign:
Do enough of the Webassign "Webassign name (select)" or "Webassign name (incremental)" so that you understand well enough to demonstrate your knowledge on a short quiz in class. If you get stuck on a problem ask yourself these questions before you give up or ask for help. (0 points)
Take a quiz on "Webassign name". Once you are done call me over to check your work.
See the warning below. (10 points)
Warning: All work shown on your Webassign quiz in class must be impeccable and include a diagram (labeled force diagram if forces are involved), all units shown at every step, and all steps neatly shown descending downwards. Any problem without all of these will receive a zero. Also, when you finish the quiz I will be asking you about why you did what you did, and if you don't convince me that you understand, then that problem will receive a zero.
Create your own problem:
Create and solve your own interesting, solvable, challenging physics problem on "Work and/or the Work Energy Principle". Particularly good problems can receive extra credit.
Include an image (jpeg or png) that you created with your problem. (The image should not include any numbers, only letters to denote distances, forces, etc.)
Within this shared google document, paste your physics problem with the image you created under the category "Work and the Work Energy Principle". Put your name at the very beginning of the problem. Call me over to see your problem and solution once it is in the shared document. (10 points)
