Introduction
 Our goal was to make a device that
allowed a ball to roll down a track
in about 15 seconds
 We used pieces of wood and
plastic tubing to construct our roller
coaster
Device Design
Place ball into the tube at the top of
stand
 Ball rolls down the tube and drops
into a funnel
 From the funnel, it goes into another
tube all the way to the bottom
 At the bottom, it hits another ball and
they roll down a ramp and into a hole

Energy Involved
Gravitational Potential Energy
stored in the ball becomes
Kinetic Energy once the ball
begins to move down the
roller coaster
The momentum of ball one is
transferred to ball two when
they collide
Conclusion
• The planning of this project took
many hours to complete as did the
actual assembly of the roller coaster.
• We encountered a problem of the ball
reaching the bottom too quickly so we
had to modify the design slightly by
changing the slope and size of the ball.
