Copy the questions/problems into your notebook if a packet hasn't been
provided. Use your data and observations to answer the following:
- What is the relationship between gravitational force and the time for
the luge run? State your answer in a complete sentence. Is the same
relationship true for the 1/2 time values?
- Which planet or cosmic body gave the fastest run? Why? Which gave
the slowest run?
- Pick one gravitational force and calculate the average speed for the
total run. Show your work. Try to convert your answer in km/sec to
km/hr. Ask for help your teacher. What is the average speed for the
first half of the run? What is the average speed for the second half
of the run?
- Do the same average speed calculation as you did in question three
for a different gravitational value. Do you see the same or
different patterns as you compare answers in question four with
those in question three?
- How is speed changing as the luge travels downward? Do you know a
name for this change in speed?
- Downhill skiers on Earth can reach speed of about 200 km/hr. What was
your average speed (in km/hr) during the last half of the run with
Earth's gravity? Can you suggest a reason or hypothesis?
- What test could you perform to test your reason or hypothesis?
- What other variable(s) would you like to change in this lab to gain
- What explanation can you give for the path of luge and rider under
zero gravity? Write your answer in complete sentences.
If a luge and rider made the run on an unknown planet and got the
following data, what value of gravity would you predict for this unknown
