For the following experiments, work in groups of no more than 3, preferably in groups of 2.  If you have a group of 4, split into groups of 2.  If you have a group of 5, split into a group of 2 and a group of 3.  If you have a group of 6, split into three groups of 2.

Both experiments can be running at the same time.  If you don't have access to the rubber bands, grab a computer.  If you don't have access to a computer, observe the rubber bands.

Rotation Experiment 2:

As accurately as possible, using the TIMER program, obtain rotational position vs. clock time data for a person spinning in a chair.

Use your data to obtain ave. angular velocity vs. midpoint clock time for each interval.

Graph average velocity vs. midpoint clock time, and using this graph everything you can about the angular acceleration of the system, including:

Sketch graphs of the following:

Continuation of Force Experiment 1:

Repeat your observations of your rubber band system.  Make no reference to the data you obtained previously.

 

Searched for at least 30 minutes. I could not find the 'Timer Program'. Instead I found a Timer (DOS) program that did times by pressing t. Also, I couldnt' find 'Supervised Study Current Semester
