| juggling item | mass | moment of inertia (about an axis that passes through its center of mass) | maximum angular force (MOI*angular deceleration) (ie. ability to break fingers) |
|---|---|---|---|
| clubs | ~200-300g | 3-7 g/m2 | we can estimate Δ angular velocity, but how long (t) does it take to decelerate? |
| 2L bottle | 2kg (by definition) | (MOI not fixed for fluids) | |
| 10pin bowling pin | 1.47kg | very high |
