Linear velociy

Linear velocity opened with a RipStik linear velocity run of 30 meters done in meters and seconds. This occupied the second half of the period - the first half was devoted to covering the quiz.

Data was recorded onto a poster pad and then entered into Desmos and analyzed.


Wednesday the students learned to use the chronographs and were to determine their walking speed by duplicating Monday's 30 meter RipStik run. No homework was assigned, but students were asked to obtain their speed from a linear regression against their split times.


Thursday the ball was rolled slow, medium, and fast with timings taken at one meter, three meter, and then five meter intervals.

Wind and rain led to experimenting with rolling the ball west. This worked well under the conditions.

The week wrapped with another quiz.
