Aluminum Inclined Plane - Constant Acceleration, 1C20.40
Topic and Concept:
Motion in One Dimension, 1C20. Uniform Acceleration
Location:
Cabinet: Mechanic (ME)
Bay: Floor Item, Mechanics South Wall
Shelf: #1
Abstract:
The steel ball baring rolling down an inclined plane demonstrates how a body accelerates at constant acceleration (a fraction of g). The metronome allows for accurate timekeeping.

Important Setup Notes:
Practice releasing the ball in sync with the beats of the metronome. The metronome time may need adjusting so that the ball hits those marks.
- The markings 1, 4, 9, 16 are distances in feet from the starting point.
- 5 minutes of setup time is needed.
- The distants between the lags is 245cm(along the incline) and the difference in hight is 16cm. This give us an angle of 3.74 degrees for the incline.
Setup and Procedure:
- Start by setting the metronome at 56 beats per minute.
- Place the ball bearing at the top of the inclined plane.
- Release. When released the ball should pass each mark on the track with the beats of the metronome. The ball should pass through #1 then hits marks 4, 9, and 16 (ie. the basket) that are marked on the side of the track.
Cautions, Warnings, or Safety Concerns:
- Please do not drop the steel ball bearings
