­Save Our Gravity Web Quest

The Problem

Gravitron, the evil warlord of Morristown West High School, has stolen all of the gravity from Jefferson County in the hopes of being able to overpower and dominate all of the Jefferson County Patriot sports teams.  In order to prevent this from happening, you (the students) must complete this Web Quest.  Gravity will only be restored once this mission has been completed and all answers and problems solved.  Good luck!  Patriot fans everywhere are depending on your success!  This message will self-destruct in 5 seconds . . . . . . . . . . . . .  or maybe not!

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 free-falling 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 Empire State Building, or from the Golden Gate Bridge, or from the Statue of Liberty, and from the top of a table, tell Gravitron how long it would take each of the balls to hit the bottom.  Fill in the table below:

 Dropped from: Time (seconds) Empire State Building Golden Gate Bridge Statue of Liberty Tabletop

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 on Jefferson County’s force of gravity.  Please give your Earth weight (in pounds) and your moon weight (also in pounds) to free our Patriot athletes to stomp the Trojans at our next game.
