Examples of harmonic oscillator in the following topics:
-
- In this atom, we will learn about the harmonic oscillator, which is one of the simplest yet most important mechanical system in physics.
- In classical mechanics, a harmonic oscillator is a system that, when displaced from its equilibrium position, experiences a restoring force, F, proportional to the displacement, x: F⃗=−kx⃗, where k is a positive constant.
- If F is the only force acting on the system, the system is called a simple harmonic oscillator, and it undergoes simple harmonic motion: sinusoidal oscillations about the equilibrium point, with a constant amplitude and a constant frequency.
- Driven harmonic oscillator: Driven harmonic oscillators are damped oscillators further affected by an externally applied force F(t).
- A solution of damped harmonic oscillator.

- The harmonic series ∑n=1∞n1 diverges because, using the natural logarithm (its derivative) and the fundamental theorem of calculus, we get:
- The above examples involving the harmonic series raise the question of whether there are monotone sequences such that f(n) decreases to 0 faster than n1but slower than n1+ε1 in the sense that:
- The integral test applied to the harmonic series.
-
- The first fourteen partial sums of the alternating harmonic series (black line segments) shown converging to the natural logarithm of 2 (red line).
-
- The integral test applied to the harmonic series.

- However, a linearization of the equations yields a solution similar to simple harmonic motion with the population of predators following that of prey by 90 degrees.
