PHY 122 Chapter Notes -Relative Change And Difference, Observational Error, Propagation Of Uncertainty
Document Summary
This experiment was done in order to determine whether the moment of inertia depends on the axis of rotation or not and to determine if energy is conserved in rotational motion. A block was placed on a rotary encoder and a string attached to that was wrapped around a pulley and data analysis was used to record the angular speed versus time of the block. The results show that both the static and dynamic moments of inertia depend on the axis of rotation of the block (as the values of the total static inertia on the short axis was 1. 489 10 4. The dynamic moment of inertia was 1. 1483 10 4 and on the long axis was. +/- 4 10 7 kg* m2 on the small and. +/- 9 10 7 kg* medium pulleys respectively and on the long axis ( 8. 7464 10 5 m2. , 9. 0599 10 5 for the small and medium pulleys respectively. )
