2. Simple harmonic motion - Wikipedia

   en.wikipedia.org/wiki/Simple_harmonic_motion

   Simple harmonic motion can be considered the one-dimensional projection of uniform circular motion. If an object moves with angular speed ω around a circle of radius r centered at the origin of the xy-plane, then its motion along each coordinate is simple harmonic motion with amplitude r and angular frequency ω.

3. Harmonic oscillator - Wikipedia

   en.wikipedia.org/wiki/Harmonic_oscillator

   The motion is periodic, repeating itself in a sinusoidal fashion with constant amplitude A. In addition to its amplitude, the motion of a simple harmonic oscillator is characterized by its period = /, the time for a single oscillation or its frequency = /, the number of cycles per unit time.

4. Harmonic motion - Wikipedia

   en.wikipedia.org/wiki/Harmonic_motion

   Harmonic motion can mean: the displacement of the particle executing oscillatory motion that can be expressed in terms of sine or cosine functions known as harmonic motion . The motion of a Harmonic oscillator (in physics), which can be: Simple harmonic motion; Complex harmonic motion; Keplers laws of planetary motion (in physics, known as the ...

6. Restoring force - Wikipedia

   en.wikipedia.org/wiki/Restoring_force

   The restoring force is often referred to in simple harmonic motion. The force responsible for restoring original size and shape is called the restoring force. [1] [2] An example is the action of a spring. An idealized spring exerts a force proportional to the amount of deformation of the spring from its equilibrium length, exerted in a ...

7. Coupling (physics) - Wikipedia

   en.wikipedia.org/wiki/Coupling_(physics)

   These equations represent the simple harmonic motion of the pendulum with an added coupling factor of the spring. [1] This behavior is also seen in certain molecules (such as CO 2 and H 2 O), wherein two of the atoms will vibrate around a central one in a similar manner. [1]

8. Lissajous curve - Wikipedia

   en.wikipedia.org/wiki/Lissajous_curve

   [1] [2] [3] Such motions may be considered as a particular kind of complex harmonic motion. The appearance of the figure is sensitive to the ratio ⁠ a / b ⁠. For a ratio of 1, when the frequencies match a=b, the figure is an ellipse, with special cases including circles (A = B, δ = ⁠ π / 2 ⁠ radians) and lines (δ = 0). A small change ...

9. Pendulum wave - Wikipedia

   en.wikipedia.org/wiki/Pendulum_wave

   A pendulum wave is an elementary physics demonstration and kinetic art comprising a number of uncoupled simple pendulums with monotonically increasing lengths. As the pendulums oscillate, they appear to produce travelling and standing waves, beating, and random motion. [1] [2] [3]
