Measuring the acceleration of gravity

Measuring the acceleration of gravity by timing the fall time for a super ball from 0, 100, 200, 300, 400, and 500 centimeters. This laboratory features a transformation of the x-axis. Squaring the time and then dividing by two and plotting against the fall distance yields a straight line with a slope equal to the acceleration of gravity. This brings a linear relationship into the heart of an acceleration measurement. This also reduces the complexity of the math down to where students with weak algebraic foundations can begin to understand the system mathematically. The lab in the text details the procedure.
