The Moon's rotation gradually slows until it synchronizes with its orbital period — always showing the same face
Orbital rate: 1.000 rad/s
Spin rate: 3.000 rad/s
Sync ratio: 3.00
Energy lost: 0%
Status: Rotating
Mechanism: The planet's gravity raises a tidal bulge on the moon. If the moon rotates faster than its orbit, the bulge leads the planet-moon line → restoring torque slows the spin. Energy dissipates as heat until ω_spin = ω_orbit (1:1 resonance).
