Lab 10: Video Analysis and Orbital Motion

Part I

First, the video analysis.

What is video analysis?  The basic idea is to look at an object in each frame of a video in order to get the x-y-time data for that object.  The program I like to use is called Tracker Video.  It is free and runs in Windows, Mac OS X, and Linux.

Here is a super-short tutorial.

So, what should you do?  You should find a video and use it to answer a question.  Let me give you a couple of hints:

Where can you get a video?  Really, anything on youtube is pretty easy to download (I can show you how to do it during class if you like).  Also, these are some other sources:
That should give you enough stuff to look for.  Oh, what about uncertainty with video analysis?  This can be tricky.  If you want to focus on thinking about a way to do this, I think that would be great.
Part II
Modeling the motion of a spacecraft.  There are three parts to this part.  All the documents and starter vpython scripts are on blackboard.
  1. Part 1: You will start with a program and model the motion of a spacecraft that only interacts with the Earth
  2. Part 2: This is similar to part 1, but it also includes the moon in the system (so it is the Earth-moon-spacecraft system)
  3. Part 3: This is similar to part 2, but you will create graphs to explore the energies of system.
Here is a video about the gravitational force, in case you forgot:
Also – here is a post about gravitational potential energy
Finally, one more bonus post.  This is about the orbital motion of the James Webb Space Telescope.
