**Discuss with your team mates how to apply "The Physics of Roller Coaster" to solve the problem. You may use the any method of communications -- MSN, discussion forum etc.**

Some questions for your team to discuss before you start your roller coaster design.


 * __ The first hill : __**

Think about the following questions when setting the height for the first hill:-
 * Is the hill height high enough to provide enough potential energy for the Coaster to make its way over the subsequent hill(s) and and through the subsequent loop(s)?
 * If the speed of the coaster is too high when it goes over the crest of a hill, what happens? Why?
 * How does a change in gravity setting affect the motion of the coaster as it goes up and down hills and around the loop?
 * Can you really change gravity on the Earth?




 * __ The subsequent hill(s) and loop(s) : __**

Think about the following questions when setting the height for the subsequent hill (s) and loops.
 * Why does the height of the subsequent hill(s) affect the ability of the coaster to go safely around loop(s)?
 * What settings for the heights of the first and subsequent hill(s) cause the coaster to either not get around the loop(s) or crash through the loop(s)?
 * Is the friction set so that the Coaster may go fast enough to make its way down hill(s) and through the loop(s)?
 * How does gravity affect the coaster’s ability to stay on the track?
