The linear force law (AKA linear restoring force law, spring force law, Hooke’s law, and simple harmonic oscillator force law) applies approximately to a wide variety of systems. In fact, almost any system from molecules to bridges and beyond obeys the linear force law for suFciently small perturbations of any component around the component’s stable equilibrium con±guration. Components moving under the linear force law alone are in simple harmonic motion. Usually some damping force a²ects the system. The linear force law in one-dimension with the stable equilibrium point at the origin is given by: a) F = − kx 1 / 2 . b) F = − kx . c) F = − kx 3 / 2 . d) F = − kx 2 . e) F = kx . 016 qmult 00110 1 1 3 easy memory: linear force law ubiquity 2. An object in stable equilibrium is subject to a restoring force. Any suFciently small displacement from stable equilibrium gives rise to a force that tries to push the object back
