At a fixed endpoint displacement, omega changes acceleration through omega squared. Exact arithmetic here means exact results for the stated model inputs; measured inputs still carry uncertainty and significant-figure limits.

One-per-second oscillator gives three acceleration units

At the right endpoint, displacement is 3 m. Omega 1 per second has square 1, so acceleration is -3 metres per second squared.

Doubling omega squares the acceleration factor

At the right endpoint, displacement is 3 m. Omega 2 per second has square 4, so acceleration is -12 metres per second squared.

Tripling omega makes nine times the factor

At the right endpoint, displacement is 3 m. Omega 3 per second has square 9, so acceleration is -27 metres per second squared.
