WebCHAPTER 15. Oscillations. Major Points. 1. In a simple harmonic oscillation the amplitude is constant and the period is. independent of the amplitude. 2. Simple harmonic motion occurs when the restoring force is proportional to. the displacement from equilibrium and in the opposite direction. WebA damping force that is proportional to the velocity (linear damping) is made by the eddy currents induced by the motion of the oscillator in a magnetic field. This magnetic damping is analogous to the effect of the resistance in an RLC circuit. Coulomb (or dry) friction is another form of damping that can occur in mechanical systems.
