Purpose: To demonstrate two dimenstional motion.

Pucks are levitated on a cushion of air to simulate motion very little friction.

The motion can be demonstrated qualitativly by simply pushing the pucks by hand and allowing the students to see the motion.

There are a large combination of various pucks that can be used to illustratate various motions and collisions. See the teaching notes for more details.

Quantitative measurements can be made by capturing the motion on video tape and then using the VideoPoint software to analyise the data.
