•The device begins by placing
a marble into the plastic
tubing.
•The marble shoots out of the
tubing into a funnel
•The marble exits the funnel
and rolls down the pvc pipe
configuration
•The marble collides with a
hotwheels car
•The car travels down the track and
strikes a platform that is balancing a lock
•The lock is attached to a string that is
wrapped around the pulley
•When the lock falls, the banner is raised
Projectile Motion:
•Marble shooting out of the plastic tubing.
Conservation of Translational and Rotational Energy:
• Marble rolling down ramp
substituting
Conservation of Linear Momentum:
• Marble colliding with the toy car
Center of Mass:
•Balancing the lock on the platform
Construction issues:
• Drilling the correct size holes in the PVC pipe
• Determining the correct height and angle of the track
• Troubleshooting the ramp apparatus to work every time
• Starting at the end and working toward the beginning to
construct the device
•More difficult than originally intended.
•Good to see how the equations work in real life
