Velocity Lab

The goal of the experiment was to examine how height and mass affect velocity.  We used a ping-pong ball and a golf ball in the experiment.  We dropped them from 1m, 2m, and 3m heights.  The golf ball had much more mass, so we figured it would drop faster and attain more velocity.  But surprisingly, the ping pong ball had more velocity in almost every test.  The ping pong ball attained a velocity of 3.3 m/s from 1m, while the golf ball had only 1.74 m/s.  They had the same velocity at 2m, at 2.15 m/s.  And at 3m, the ping pong ball had a velocity of 2.05 m/s, while the golf ball only managed 1.88 m/s.

We then compared our "Amish" results with a motion sensor. The graphs that came up showed the time as an equation of time. The ping pong ball is first.

The oddness after 1.5 seconds on the golf ball was me catching it, so it recorded my hand instead of the ball, just FYI.
