PURPOSE:
To give the student experience in data gathering and calculations based on actual amusement ride physics.

INTRODUCTION:
The "Pendulum" is a fairly new ride found at many amusement parks. It consists of a central tower with a strong wire attached at the top extending down to a platform where the riders (1 -  3) lay.  A pull wire is attached to the platform and is pulled upward in an arc from a second shorter tower. The platform is released and the platform swings in a typical pendulum arc.

A protractor will allow you to measure angles.

PROCEDURE:

1) You can adjust the background shading by clicking on the "Special" button to the right and selecting "Background". Click on the "Special" button and select "Print Blank Report" to obtain a web page that can be printed and used as a lab report. (the program will not be interrupted)

2) Record the mass of the platform and riders. Click on the button and reset the platform. Drag the protractor over and measure the angle the wire connected to the platform makes. Record.

3) Start the platform swinging in its pendulous arc. When the platform swings as far to the left as it can, start the stopwatch. Allow the platform to swing all the way to the right and then back as far as it can to the left. Stop the stopwatch. The time it takes to move all the way to the right and back again is called the pendulum's period. You may want to repeat this procedure and take an average of several attempts. Record.

4) Note: all friction is ignored in this lab and the wire that supports the platform is considered stiff and nonflexable.

5) Calculate the requested values asked for on the lab sheet and any given by your teacher. For help on these values click on the "Special" button and select "View Data & Hints". Select "File Report" to send a copy to be viewed by your teacher.
