Assignment: Angular Kinetics

The giant swing is a good example of angular rotation. This homework will help you understand how a gymnast starting with a velocity of zero is able to complete a full rotation around the bar while friction and air resistance are working against the motion.

Giant swing that you will analyze

Data collection for giant swing (Time between frames = 1/15 s)
We will create charts of angular velocity versus angular position, linear velocity versus angular position, and radius versus angular position.

The following videos will help you create your spreadsheet. The demo uses a hammer throw rotation rather than a giant swing but the steps are the same with the following execptions.

• Your first column uses frame numbers rather than time
• The transition between quadrants happens at different times
• The time for the velocity formula will be (2/15)s rather than (2/60)s
