Physics I Experiment 1122
Note criteria below for grading of lab reports:
1. Gave the pertinent details of the setup. 10 pts.
2. Stated what we were trying to observe or test. 10 pts.
3. Reported sufficient and pertinent data. 10 pts.
4. Told the reader what the data mean. 10 pts.
5. Communicated the method of analysis. 20 pts.
6. Analysis was correct and complete. 20 pts.
7. Presented the desired final results in an appropriate organized form. 10 pts.
8. Told the reader what conclusions were reached. 10 pts.
Give the 'rotation wheel', with all the bolts inserted, a spin and take data to determine its initial angular velocity and its angular acceleration, assuming constant angular acceleration.
Take the data necessary to determine whether angular acceleration really is consistent at different angular velocities.
Measure the diameter of the axel.
Take the data you will need to determine initial angular velocity vs. angular acceleration for the wheel with the outermost four bolts removed.
Analysis: Figure out how much energy you put into the wheel for each spin and make a good estimate of how much torque you applied to get it spinning, as well as the force you had to exert to rotate the axle.

The density of a metal sphere with radius 15 cm, in grams / cm^3, is .7.5. The sphere is rotated about an axis thru its center.
