Project Introduction

• Goal: To Create a Complicated Machine that can stamp a piece of paper

• Requirements: Demonstrate Conservation of Momentum, Conservation of Energy, and Projectile Motion

• Budget: $20 maximum

Expenses

• Rat/Small Rodent Trap: $4.50

• Marble(s): $2.50

• Funnel: $1.50

• Projectile Launcher: $1.00

• Stamp: $.50

• Wood base: $4.50

Project Overview

• Projectile is launched at an angle and collides with the marble forcing it to begin down the track.

• The marble then rolls down the track, through the funnel and down the second track.

• The marble then falls onto the trap release, which stamps the paper.

Energy Conversions

• Spring– Elastic Potential Energy and Gravitational

Potential Energy to kinetic energy

• Projectile– Kinetic Energy and Gravitational Potential

Energy which is conserved and transferred with Conservation of Momentum

• Marble– Gravitational and Kinetic Energy to just Kinetic

• Rat/Small Rodent Trap Spring

Conclusion

• The Crusher took 4 and a half hours to construct– Problems encountered:

• Splitting wood• Energy Loss (Hard to account for)• Mouse trap

• We feel that our design was a success• We learned how coming together as a team can

help to solve problems and bring in new ideas
