- 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.
- 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.
- 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.
- 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.
