The simplest type of oscillations are related to systems that can be described by Hooke’s law, F = −kx, where F is the restoring force, x is the displacement from equilibrium or deformation, and k is the force constant of the system.
An example of a simple harmonic oscillator is the simple pendulum, as shown in the diagram above. The pendulum oscillates around a central midpoint known as the equilibrium position. Marked on the diagram by an x is the measure of displacement, and by an A is the amplitude of the oscillations, this is the maximum displacement.

Examples of systems which experience free oscillations are: Simple pendulum - A small, dense bob that hangs from a string, which is attached to a fixed point. Once the bob is displaced and let go, the pendulum will oscillate freely. Mass-spring system - A mass attached to a spring, which will oscillate freely once displaced and released.
24 Απρ 2022 · Oscillations in a Potential Energy Landscape. The potential energy associated with a mass on a spring has a very simple form: \(U_{\mathrm{s}}(x)=\frac{1}{2} k x^{2}\) (see Equation 3.3.7). The potential energy landscape of a harmonic oscillator thus has the shape of a parabola.
Introduction to Oscillations and Waves covers the basic mathematics and physics of oscillatory and wave phenomena. By the end of the course, students should be able to explain why oscillations appear in many near equilibrium systems, the various mathematical properties of those oscillations in various contexts, how ….

1. One of the most important examples of periodic motion is simple harmonic motion (SHM), in which some physical quantity varies sinusoidally. Suppose a function of time has the form of a sine wave function, y(t) = Asin(2πt / T ) (23.1.1) where A > 0 is the amplitude (maximum value).
