## harmonic motion

n.
A periodic vibration, as of a pendulum, in which the motions are symmetrical about a region of equilibrium. Such a vibration may have only one frequency and amplitude or may be a combination of two or more components. Also called periodic motion, simple harmonic motion.

## harmonic motion

n
(General Physics) a periodic motion in which the displacement is symmetrical about a point or a periodic motion that is composed of such motions. See also simple harmonic motion

This active harmonic approach gave more harmonic freedom compared to Overture, which follows a more static harmonic motion. In addition, this sense of Afro-Cuban lowness and deepness in the piano register is a permanent aspect of all my compositions that I use to celebrate my African ancestors' old spiritual omnipresence, as in the piece Overture.
Then, teachers can guide their students on how to make innovative use of the smartphone for explaining, relating and reflecting the principle of simple harmonic motion (SHM) in the playground.
He applies the general language of harmonic motion to magnetic dynamic phenomena in magneto-ordered systems in order to analyze the magnetic dynamics from a more general point of view and find some useful mathematical analogies with other dynamic systems.
A shear wave propagates vertically through the free field soil, which induces the horizontal harmonic motion and horizontal displacements.
The mechanism of this instrument is based on generation of high-frequency harmonic motion of metallic rods which break hydrogen bonds and denatures proteins at the tissue interface with resultant sticky coagulum that seals off blood vessels.
"American Serenade," by Louis Alter, uses a combination of Liszt and Debussy influences with technical passagework and parallel harmonic motion. "American Waltz," by Peter De Rose, creates a nice lilt with cadenza-like interruptions.
As is well known (in no small part through Haimo's 1990 essay on the topic in Musical Quarterly), Haydn increasingly made use of distant harmonic motion in the 1780s and 1790s.
One of the reasons this problem is so common is that the answer, the predicted equation of motion of the test object, is yet another instance of simple harmonic motion. What is rarely pointed out, however, is that we presently lack direct empirical evidence to verify the theoretical prediction.
