Abstract:

Using video analysis software such as Tracker and inexpensive highspeed video cameras, students can do very interesting projects at the introductory level. In this presentation, I will demonstrate two projects completed by students in my introductory calculusbased physics class. (1) Highspeed video analysis of a soccer ball kicked with backspin was used to measure the force and torque on the soccer ball by the foot. The force and torque were used to calculate how far off center the foot impacted the ball, i.e. the moment arm. (2) A mechanical device was used to model a hula hoop rotating around a person's arm. Highspeed video analysis of a hula hoop rotating on the device showed that a point on the hoop travels in a spirallike path. A graph of xposition vs. time for a point on the hoop was a sum of two sine curves of similar frequencies, similar to a beat pattern in acoustics.
