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

INTRODUCTION:
"Go Carts" are a favorite for many amusement park visitors. These little low center of gravity carts whiz around oval tracks at fairly fast speeds.

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) Drag the tape measure near the left most red line, that crosses the bottom of the track, and then click on its red button. Drag the tape body 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 two red lines on the track.

3) The upper left hand corner of the track forms an arc based on a circle, as shown in outline. Measure and record the radius of this circle.

4) Start the go cart. Use the stop watch to measure the time it takes for the cart to travel the distance between the two red lines on the bottom of the track. Repeat this measurement and record the average time. At this time the cart is traveling at a constant velocity.

5) Click on the "brake next pass" button. When the cart reaches the left red line, on the track, it will lock up its brakes and start to skid to a halt. Measure and record the distance it takes for the cart to stop.

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.
