2. Design Two layer rollercoaster Starts from rest Dropped into a loop
Proceeds into a spiral
Drops down into a pipe
Makes a jump into a funnel
Shoots down a tube
Hits a magnetic target.

3. Stored Energy
Potential Energy = Mass · Gravity · Height Marble starts from rest Marble is dropped All stored energy is potential energy (mgh) Energy = (.003 kg)(9.81 m/s²)(1.05 meters) Energy = Joules

4. Design and Construction Issues

5. Conclusions Our elevator was good in theory, not in practice
Cross-bracing was an effective means of supporting our structure
We learned not to overcomplicate our designs when given basic materials to work with.
A good team has to adapt to dynamic problems
