I showed a demonstration of projectile motion with air resistance and orbital motion.Īs with any workshop, there are unexpected issues that come up.

I have more programs to go over, but in both workshops we were running out of time.

The teachers are given the program of the ball tossed in the air (from the previous example) and then they need to make it a program with a ball tossed at angle. There is no homework for the participants, this is just a demo. After that I show a simple example of a ball tossed in the air (straight up) with 3D visualizations. I show the VPython objects: sphere, box, arrow. I have a sample code, but I don't give them any questions to work on. This is just a demonstration of how VPython handles vectors. After they get the program running, there are some questions to suggest things they could change. I show what the output should look like and then give the participants code with some parts missing. This is a short mini-lecture in which I show both how to model the force due to a stretched spring and then how to make a python model of a mass oscillating on a vertical spring. First, I show how to add a graph to the same constant acceleration problem and then I give the teachers a problem with two moving objects and they use a graph to find when these objects meet. This is essentially the same as the program above but with a non-zero acceleration.

An object moving in 1D with a constant acceleration.

The results are printed out and there are no graphs and no 3D elements. Note: I decided to start off with very simple code. Go over the code and then give the participants an opportunity to change the code to answer some homework questions.

Start with an object moving at a constant velocity and in one dimension.
