For this project, you will create a poster that diagrams a made up
roller coaster. This roller coaster will contain calculations of g's,
velocities, heights, spring constants, etc.
No late papers accepted.
This counts as a lab grade.
You may work in groups of 2 or by yourself.
Neatly drawn with a magic
straight lines drawn with a straight edge or computer
smooth curves drawn with drawing aides or a computer
no white out
virtually no smudges
grid lines drawn every set distance with a ball point pen
bigger than 10" X 13"
smaller than 30" X 36"
Must be drawn on poster board or
mounted to poster board
The board must have the coaster
without any numbers drawn on it.
The board must have a plastic sheet
- The cover contains all numbers and answers. These numbers are
to be placed at the corresponding locations on the coaster
- The plastic cover must be attached only at the top of the
Every hill, dip and loop top and
Calculate and label the velocity, centripetal acceleration expressed
in m/s2, and the g's felt by the rider.
Every linear force (either from a
graph or pure number)
Calculate and label the force at the beginning where the force is
applied and at the end of where the force is applied. Also calculate
the acceleration of the due to this force expressed in m/s2 and
Calculate and label the spring constant.
Calculate and label maximum compression distance of the spring.
Calculate and label the velocity of the coaster's car before it hits
EVERY SINGLE CALCULATION must be
NEATLY written on a 1/2 sheet of paper.
Maximum positive g's must be less
than 10 g's to be considered for an "A" grade.
Maximum negative g's must be less
than 4 g's to be considered for an "A" grade.
Must contain at least one loop
Must contain one spring OR
force that does work -whose force is calculated from a graph.
Grades are based on the neatness of your presentation and the
correctness of your work. It is hard to get an "A." An "A" project
follows all the rules above and is creative. It is the exemplary
project. It is easier to get a "B."
