Fr.: mouvement harmonique   

The motion of a body subjected to a restraining force which is directly proportional to the displacement from a fixed point in the line of motion. The equation of simple harmonic motion is given by x = A sin(ωt + θ0), where x is the body's displacement from equilibrium position, A is the → amplitude, or the magnitude of harmonic oscillations, ω is the → angular frequency, t is the time elapsed, and θ0 is the → initial phase angle.

simple; → harmonic; → motion.

simple harmonic oscillator
  نوشگر ِ هماهنگ ِ ساده

Fr.: oscillateur harmonique simple   

An oscillator whose force is proportional to its extension, according to → Hooke's law. The way the oscillator moves is called → simple harmonic motion.

simple; → harmonic; → oscillator.
