Rotational Derby
Spinning Ruler and Coins Lab (Use Cart Springs as Impulse)
Calculating Moment of Inertia Lab
Steps:
1. Use poles and connecting blocks to create an irregular shaped object.
2. Use a piece of tape and draw an x/y coordinate plane to indicate the axis of rotation. Because the object rotates in three space, the 'z' axis will be considered the axis of rotation.
3. Calculate the moment of inertia for your object rotating about the 'z' axis.
4. Go around the room and calculate the moment of inertia for at least 2 other groups.
5. Show your work and turn in your work into the period basket.

PVC Pipe Rotational Dynamics Lab
*Students will have one full class period to collect data. Students should then complete the remainder of the lab as homework.
*Students do not need to count the number of rotations. Calculate angular acceleration based on the linear acceleration of the hanging mass and the radius of the PVC pipe.
*The moment of inertia for the PVC pipe structure will be a small number.

PVC Pipe Rotational Energy Lab
*Students need to count the number of rotations while the hanging mass drops.
*Students should use FINAL angular velocity and FINAL linear velocity in the energy conservation equation.
