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