Our Machine in Action:
A Rube Goldberg is a contraption, invention, or device that is deliberately overdone and engineered to complete a simple task, usually in a chain reaction.

Driving Question: How can we model the mathematics behind motion, forces and energy using simple machines?
Gravitational Force

Friction Force

Electric Force

Normal Force
Linear Motion

Rotational

Ball is a "no-go"
Machine is simpler than other machines
We are the ending team
There is a chance that the marble wont trigger our team
Bowling ball
Ramp is elevated
Lights are fragile
Lights heat up really fast
Marble connection from team nine
The projector is really bright
Make bowling ball more appealing
Hide wires of makey makey
New Tech Sign
Bowling ball travel down special bowling ball ramp
No small ball or PVC pipe
At the end of machine
New Tech sign

Our slope:
3/132.2 cm
9.6 cm (height)
12.6 cm (height)
132.2 cm (length)
Our Conclusion:
How can we model the mathematics behind motion, forces, and energy using simple machines?
-How steep a line is
- Slope= rise/run
What is it?
Slope:
The Calculations
Difficulties with ramp
Energy
Potential

Kinetic
Bravo!
