Car takes off down “Hot Wheels” track once it is released
by a small piece of wood.
Then goes through a loop and is launched and hits a
“paddle”.
The paddle hits a “Fanta” can that is balanced using
water and its center of mass.
The can then falls down and the water flows out down
the PVC chute and into a cup.
The cup is attached to two pulleys with string that are
connected to the banner.
Once the cup is filled with the correct amount of water it
descends while pulling up the banner.
Walking through the motions
• Car starts with Gravitational Potential Energy
• Picks up Kinetic Energy as it goes through the
track
• Car travels around loop utilizing circular motion
• Linear momentum of the car is conserved and
creates a torque in the paddle knocking over the
can
• The can is balanced using its center of mass
Calculations
• mgh = .5mv^2 + mgh From point A to B
• This step made sure car was placed high enough
• Sqrt(2gh) = Vcar
• This calculates the speed car will leave ramp
• Then we calculated torque to hit the can
balanced on its center of mass
• Then the can’s water pulled the cup down
lifting the banner using angular momentum
Difficulties
• Finding a time that everyone could meet
up
• Finding the materials needed to build
• Limited resources
Conclusion
• Overall the project went well and we
completed in the time allotted
• The team achieved the goal and created a
working Rube-Goldberg Device
