The 3 pages that link to Restoring force, each with the reason it gives.

• Simple harmonic motionNarrower topic: Simple harmonic motion is the special case where this force grows linearly with displacement.

• Harmonic oscillatorNarrower topic: The oscillator is a special case with a restoring force linear in displacement.

• AnharmonicityRelated: A nonlinear restoring force is the dynamical counterpart of a nonquadratic potential.
