Now is the time for the vpython standard (I am now calling it the Numerical Calculations standard). I am making it due on Feb 15 – so you have some time. Here is what I want:
A 5 minute or less screen cast that shows me a numerical calculation. I would suggest using VPython (or Glowscript or trinket.io), but you can use whatever you want. Here are some notes:
- Here is a rough scoring guide:
- 5 points: this is a numerical solution to an interesting problem that can’t be solved analytically. Also, the screen cast will include evidence that suggests the calculation is valid (like looking at the extreme cases of low mass or whatever)
- 4 points: this is a numerical solution for a problem with non constant forces
- 3 points: this is a numerical solution for something fairly trivial, like a constant force motion
If you go through the tutorials I posted on moodle, you should be able to at least get a 4. Here are some other notes:
- I hate to make you create a screencast, but I think this is the best.
- You need to show your screencast to two other people before you send it to me.
- One way to share your screencast would be to just post the link in moodle.
- If you absolutely don’t want to make a screencast, you can show your program in class instead.
- Don’t forget to submit this on time. If you do, you can always fix stuff and resubmit it.
- If you get stuck, ask for help.

- Repeat of what we did in class (essentially) https://www.wired.com/2014/07/how-do-you-model-a-spring/

I don’t expect you to memorize everything. I will try to let you know what things you need to remember and what I will give you. For chapter 2, here are the equations that will be provided.
I am going to talk about vectors in class using python. If you want to look at something similar – either before or after class, check this out:
