Experiment 3 Free Fall Analysis Objective To determine gravitational acceleration by studying the velocity of a falling object as a function of time. Theory An object that is only acted on by gravity is said to be in free-fall. Near the surface of the Earth the magnitude of acceleration due to gravity is given by g , and is nearly constant with a measured value of 9 . 81 ± 0 . 02 (where the uncertainty comes from differences in elevation

The acceleration is related to the velocity of an object and the velocity is related to the displacement of an object through the denitions: ~a ( t ) d~v ( t ) dt and ~v ( t ) d~x ( t ) dt 19...
