The Big Ideas—Chapter 13 (Serway and Beichner, Physics for Scientists and Engineers, 5 th Edition) AJM:1/4/01 1 Sections 1 and 2 When a particle is subject to a net restoring force that is purely a linear function of the displacement from an equilibrium position, the particle will execute simple harmonic motion about the equilibrium position. Simple harmonic motion has the following specific characteristics: 1 The particle’s displacement from the equilibrium position is a sinusoidal function of time. 2 The period of motion is determined exclusively by the stiffness of the restoring force and the inertial mass of the particle. Notably, it does not depend on the amplitude of the motion. 3 The velocity amplitude is equal to the angular frequency of the motion times the displacement amplitude (usually just called “the amplitude.”) 3 The acceleration amplitude is equal to the angular frequency of the motion times the velocity amplitude. The amplitude and the phase of the sinusoidal motion are determined by the initial conditions of the specific motion under consideration. F
