PURPOSE: To Show Uniform Acceleration.
DESCRIPTION: A Galileo track is marked at equal time intervals. The track is tilted on an incline. A metronome is wound up and set to 69 for room 166 and 63 for room 168. The metronome is released to rhythmically tick. An orange science ball is carefully released so that the ball is synchronized with the metronome. On each tick of the metronome the ball will pass each mark on the track. Thorough practice by faculty is necessary OR the demonstrator must perform the experiment to assure good results.

EQUIPMENT: The Galileo's Inclined plane is stored in mechanics against the wall behind the cabinet, the metronome is stored in the general use, the science ball is in the mechanic's marbles/balls drawer.
SETUP NOTES: This is not easy to perform and requires practice AT THE SPOT IN THE CLASS so that the correct tilt angle of the track is adjusted to the angle on the floor.
