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

INTRODUCTION:
The "Bumper Car" is a ride found in many modern amusement parks.  It consists of a group of motorized cars that inevitably collide with one another.

Two bumper cars.

A tape measure will allow you to determine distance.

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 blue and green cars.

3) Place the tape measure near the blue car and then click on its red button. Click and drag the tape to the right and notice that the yellow tape is pulled out. Click once again on the tape measures red button to lock it in place. Measure and record the distance between the blue and green cars.

4) Press on the top button of the stopwatch to start the blue car moving. At the point when the two cars collide, press the button again to stop the watch. Take 5 readings and calculate their average. Record.

5) Note: friction is not considered in the calculations for this lab nor do the cars continue on with their new velocity, as they would in real life. This is an elastic collision.

6) 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.
