The Task
You, as a member of the Jefferson County Gravity Alliance, must use the web links that are provided on this web page to answer each of the following questions about gravity. Write down, on a sheet of paper, the answer to each question.
The Process
1. In his famous experiment on gravity, Galileo dropped objects from what famous landmark?
2. What are the two characteristics of a freefalling object?
3. Scalars and vectors are similar, but not exactly the same kind of measurements. To confuse Gravitron, explain the difference between these two terms?
4. Gravitron can be weakened by explaining the difference between distance and displacement. What is the difference?
5. Find the mathematical formula for calculating acceleration.
6. If the velocity is constant, describe the slope of the graph on a position vs. time graph.
7. If a ball was
dropped from the
Dropped from:

8. According to the popular story, how did Sir Isaac Newton come up with his Universal Law of Gravitation?
9. To further confuse Gravitron, we need two meanings for the word gravity that have absolutely nothing to do with math or science. What are the two other meanings?
10. Once all other
questions have been answered, if you can give your weight on the Earth and your
exact weight if you were on the moon, you can successfully end Gravitron’s hold

Evaluation
After
successfully finding the answers to the above gravity questions and writing
them down on your paper, you will hand them in to your Gravity Leader (your
teacher). You will be given gravity
points for each correct answer, and your total gravity rating (your grade) will
be determined by how many of the 18 required answers you successfully found. For example, if you answer 9 of the 18
questions correctly your gravity rating would be 50%. In order to get a passing grade you must
answer twelve of the questions correctly.
Conclusion
Congratulations! You have stopped Gravitron from his attempt
to eliminate the
