written by Anne Cox

The Projectile Motion with Angry Birds lab uses the Tracker video analysis tool to measure and analyze the motion an angry bird projected from a slingshot to hit a pig.

The trz file contains the lab handout, a video, and a Tracker tab file.

Credits: The original video came from Rovio, the makers of Angry Birds: http://www.youtube.com/watch?v=9-hjAY0XpvE. This exercise was inspired by Rhett Allain's Dot Physics, a physics blog for Wired.

question about acquisition of video

Hello,

I was wondering how you got the videos off of the internet. Did you download them from youtube, or did you get them some other way?

Thanks,

There are several options to get a video to analyze.  I think the best is to use the free Angry Birds game in the chrome browser - http://chrome.angrybirds.com/.  With this, you could use a screen capture program to record the screen (I use Quicktime in Mac OS X).

If you want to download a video from youtube, I use the Chrome Youtube Downloader extension - but there are many other youtube downloaders if you search.

Of course there is one other way to get the video.  You can always play Angry Birds on a phone or tablet and record the motion with another camera.

unable to understand how to create a shifting axes accordingly to a fixed point

in the analysis, the edge of the grass is used an a reference point, probably it has something to do with the offset origin.
is there a step by step tutorial that shows how it is done correctly.
i am having some difficulties making a axes that shifts according to the offset origin.
thanks!

In Tracker Video analysis, be sure to "coordinate system" at the top and uncheck "fixed origin". After that you should be able to step through the video and move the origin to the correct location.
