A.4.6 (HL)—Moment of inertia Topic Practice
A.4.6 (HL)—Moment of inertia Topic Practice
Practise defining and calculating moment of inertia for stated axes, then linking mass distribution to angular acceleration.
How this is tested
- define moment of inertia with I = sum mr^2 for a stated axis using perpendicular distance r
- substitute the correct model equation for a rod or cylinder and give units of kg m^2
- compare ring and disk models by linking larger I to smaller angular acceleration
