Lab: Measuring Rotational Inertia by Rolling
Watch it explained
- How it worksWalk me through turning a measured rolling acceleration into an inertia coefficient.
- How it worksHow does plotting final speed squared against release height straighten the data out?
- Worked exampleFind the inertia coefficient of an object reaching 2.6 m/s after rolling down 0.75 m.
- Going furtherWhat does a slower than predicted roll tell you about slipping or about axle friction?
