050 RipStik change in momentum is force
This exercise requires eight to ten stopwatches, the eight meter tape measure, red spring scale, red yarn, chalk, RipStik. The theory was presented up front along with a diagram of the demonstration. After this the class moved to the sidewalk to gather data. The red yarn and red 20 Newton spring scale was used to obtain a force of 10 ± 2 Newtons. As last spring, all work was done on the whiteboard. Median time calculations. Maicalany recording a speed trap time on the board after the run. After class the data was entered into a spreadsheet that tracks 050 experiments. The 31% difference was the largest seen for this demonstration in the two prior terms in which this version was performed. Reference photos are available from last spring . To be fair, the demonstration came on the heels of a memorial service the evening before and the rider was not ready to make this run.
