Atwood Machine

Students set up an Atwood machine using a Wireless Smart Gate and pulley. They collect acceleration data for a system, keeping the total mass constant while varying the difference in the weight of the two hanging masses. They graph the difference in the weight versus the acceleration and discover the slope is the total mass. The equation of their line allows them to make predictions about the acceleration of an Atwood machine they did not measure.
