 Goal
of our project was to create a
rollercoaster-like contraption to move an
object from one place to another and take
as close to 15 seconds as possible.
 Materials used that were not purchased
would be plain paper, scotch tape, and
wood screws.
 Only purchased material was two types of
plywood and a piece of compressed wood.
 Total cost was around 10 dollars.
 Our
rollercoaster is a shallow box that
stands nearly vertical and has sloped
shelves that the ball rolls on.
 The ball is dropped through a hole at the
top of the box, then rolls down the shelf
where it drops to a different shelf below it
that is sloped downward in the opposite
direction.
 After rolling down seven shelves, the ball is
stopped by a wad of gum to create a
perfectly in-elastic collision which stops the
ball.
Total build time for our project was around 6
hours. The majority of this time was building and
testing. The rest was planning the building of our
rollercoaster, creating our presentation and
writing our report.
 Problems we had were:
- Faults in the wood created problems for us
resulting in the need for slight modifications.
- A level surface was required in order for our
rollercoaster to run correctly.

– Starts out at gravitational potential
energy and then goes to kinetic energy.
