Wireless Rotary Motion Sensor
Experiment 2: Rotational Inertia of Disk and
20
013-15949A
4.
Calculate the experimental value of the rotational inertia of the disk alone and record the value in Data Table 3.
5.
Subtract the rotational inertia of the disk from the total rotational inertia of the ring and disk, and record this as
the rotational inertia of the ring alone.
6.
Use a percent difference to compare the experimental values to the theoretical values.
