Measuring g by Flow Rate

written by Gregor Steele

A Tracker experiment that analyzes an image of a water stream to determine the acceleration due to gravity, g. The the image shows that the diameter of a water stream decreases as it falls. Since the flow rate is constant, we can measure the diameter at different heights to determine the value of the gravitational acceleration.
