Energy of a Simple Harmonic Oscillator: Energy Of A Simple Harmonic Oscillator Quiz
A simple harmonic oscillator is a system that undergoes periodic motion under the influence of a restoring force proportional to its displacement from equilibrium. The equation of motion for a simple harmonic oscillator is given by:
$m\fracd^2xdt^2 =

where mis the mass of the oscillator, kis the spring constant, and xis the displacement from equilibrium.
The energy of a simple harmonic oscillator is given by:
$E = \frac12kx^2 + \frac12mv^2$
where vis the velocity of the oscillator.
The amplitude of the oscillator is the maximum displacement from equilibrium. The frequency of the oscillator is the number of oscillations per second. The period of the oscillator is the time it takes for one complete oscillation.
An example of a simple harmonic oscillator is a mass attached to a spring. The energy of the oscillator is determined by the amplitude, frequency, and mass of the oscillator.
Potential and Kinetic Energy in a Simple Harmonic Oscillator, Energy of a simple harmonic oscillator quiz
The potential energy of a simple harmonic oscillator is given by:
$U = \frac12kx^2$
The kinetic energy of a simple harmonic oscillator is given by:
$K = \frac12mv^2$
The potential and kinetic energy of a simple harmonic oscillator vary with time and position. The potential energy is maximum at the equilibrium position and decreases as the oscillator moves away from equilibrium. The kinetic energy is zero at the equilibrium position and increases as the oscillator moves away from equilibrium.

Total Energy of a Simple Harmonic Oscillator
The total energy of a simple harmonic oscillator is the sum of its potential and kinetic energy:
$E = U + K = \frac12kx^2 + \frac12mv^2$
The total energy of a simple harmonic oscillator is constant. This is because the potential energy is converted into kinetic energy and vice versa as the oscillator moves.
