Today in Physics we are doing the "Constant Velocity" Lab. Students are given windup toys and are tasked with determining whether they are moving at a constant velocity. The method is fairly straight forward. Put the windup toy on a piece of paper and make a mark to show its position every second. Students then graph the data on their graphing calculators and find the equation of their best fit line.
In-order to get our 1 second intervals I set up a click track in Audacity. Just select "Click Track" from the "Generate" menu. Then set it to 60 beats/minute with 10 beat measures. It doesn't really matter how many measures, but if you have lots you might crash the program. I usually just create 6 measures (1 minute) and the hold the Shift key down when I hit play so it will loop continuously.
