This experiment uses the computer/multimedia system to measure the time between interruptions of a laser beam. A laser beam is bounced from multiple mirrors until it enters a detector at the far right end of the table. Each time the laser beam is broken an event is recorded by the computer and this data can be used to calculate the velocity and acceleration of a person moving through the detection zone.
