Projectile Motion

I was reading this post on Dan Meyer's amazing blog a while ago and thought it was great.

Then a while later I saw these amazing light paintings from the exploratorium and had an idea!

By throwing my bicycle light and taking a long exposure photograph I was able to get this image of a beautiful parabola.

After importing it into geogebra and looking at the projectile motion wiki, I made this:

This is a Java Applet created using GeoGebra from www.geogebra.org - it looks like you don't have Java installed, please go to www.java.com

If I had marked distance it would have been interesting to try and find the velocity I threw it.

This was also inspired by Radiolabs parabolas video.
