Alpha Ledger Cites Checked Sources - Rotational Dynamics: Torque, Inertia, and Angular Momentum Step by Step

The acceleration claim is part of a typed source chain. Exact arithmetic here means exact results for the stated model inputs; measured inputs still carry uncertainty and significant-figure limits.

highlighted = computed this step

Later ledgers can reuse the same inertia source

The source ledger keeps inertia 6 tied to the same checked point-mass recipe used for alpha.

I=6\ \mathrm{kg\,m^2}

The angular-acceleration source references are explicit

The alpha ledger stores 2 source references: torque and inertia.
