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.
highlighted = computed this step
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.
a=(−ω2)x=−1×3=−3
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.
a=(−ω2)x=−4×3=−12
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.
