4. Subtract the rotational inertia of the apparatus from the combined rotational inertia of the point
mass and apparatus. This will be the rotational inertia of the point mass alone. Record in Table
2.3.
5. Calculate the theoretical value of the rotational inertia of the point mass. Record in Table 2.3.
6. Use a percent difference to compare the experimental value to the theoretical value. Record in
Table 2.3.
