1. “The Slow Mojo” Team One:
Bradley Davis, Emily Smith, Aaron Howard, Zachariah McPherson

2. Overview Conservation of Translational Energy
Conservation of Rotational Energy
Center of Mass
Torque
5 Steps + Trigger
Actual Cost: $9.00
Projected Cost: $16.00

3. Conservation of Energy
Variables: mass (m), gravity (g), height (h), velocity (v), inertia (I), and angular velocity ()
Marble Launcher
Potential = Kinetic + Rotational
mgh = (1/2)mv2 + (1/2)I2
V = 5.61 (m/s)
Car on Wedge/Ramp
Rotation of Tires Included
V = 1.40 (m/s)

4. Center of Mass Scale/Balance 7 Marbles Mass (m) & Radius (r)
mr1 > mr2 (first equation)
r1 + r2 = 0.25 m (second equation)
Used simultaneous equations
r1 = 0.17m & r2 = 0.08 m

5. Torque Razor VS String  = I (torque, inertia, acceleration)
I = (1/3)mL2 (inertia, mass, momentum )
Constant Acceleration (angular)
 = N-m
 = 113 rad/sec2
