Rotating strap

For the strap rotating about the threaded rod, give your data indicating through how many degrees it rotated, how long it took and the average number of degrees per second.  Report one trial per line, with a line containing three numbers, the number of degrees, the number of seconds, and the average number of degrees per second, separated by commas.

Rotating strap:

Let the strap rotate on the threaded rod, as before.  Click the TIMER at the start, and then at 180 degree and/or  360 degree intervals (the latter if it's moving too fast to do the former).  Copy the output of the TIMER program below:

On the average through how many degrees per second was the strap rotating during each interval?  Report in a single line, giving the numbers separated by commas.  Starting in the second line explain how you did your calculations.

The second column of the TIMER output shows the clock times.  For a given interval the 'midpoint clock time' is the clock time in the middle of the interval.  Report clock times at the beginning, middle and end of your first interval in the first line below.  Do the same for your second interval, in the second line.  Starting in the third line explain how you got your results.
