Lab Procedure

  1. Before starting your run, you must first choose the amount of gravity by clicking on the edge of the Gravity Selection Box. As you point and click on a position, your chosen value will appear in the box below, and an example of a body which has gravity close to the value which you've chosen. Also, your chosen value will automatically be recorded in the Data Table when you start the run.

  2. Next, click on the Start Run button. You will immediately see the luge and rider begin the descent. You may click on the luge at any point for an instantaneous measurement of speed, distance, and time. If you need this information, make a record of it in your notebook. Note: You will be recording time, speed, and distance. Your chart is not labeled this way. As the luge passes the mid-point flag, the time at mid-point will be given, along with a picture of the luge and rider. As the luge passes the finish line, the total time will be given. Both the mid-point and final times will be automatically recorded in the Data Table. However, if you made any instantaneous measurements during the run, these would have to have been recorded manually when you took them.

  3. To repeat a run using the same value of gravity, click on the Repeat Run button. If you want to change the gravity, do this before clicking on the Repeat Run button. It is suggested that for each value of gravity, you make at least 3 trial runs.

  4. After you have collected data for at least 5 different values of gravity, you are ready to use this data to proceed to a series of questions and problems to allow you to apply what you have learned. To move to this section of the lesson, click on the Analysis button. Be sure you have transfered all of your data to your lab packet or notebook.
