What is a harmonious movement?

Harmonic movement is the concept of an oscillating or recurring system such as a pendulum, spring or orbit of the planet around the Sun. Systems that are in harmonious movement save energy and momentum if the internal energy remains the same. In the actual system, ie non -ideal, energy is lost due to friction even in infinite quantities due to collision with molecules. There must be two main features for the system to experience oscillating movement: elasticity and inertia; Given the first law of Newton, all objects have inertia. Therefore, there must be a source of elasticity such as a spring. The movement of the object changes speed in a sinusoidal pattern. The elastic force that provides the mobility of the object increases with the distance from the center of movement; The farther is the object, the more elastic force is developed. When the object comes to the end of its movement, the strength causes it to move backwards to increase speed to the other end of the oscillating path, where the cycle is repeated. A simple H is used to illustrate the conceptAronic movement, but does not take into account friction.

insertion comparison involves friction or other external forces that slow down the system and eventually cause it to achieve balance or without movement. The more friction is in the system, the faster the oscillating object reaches balance. Only a few cycles of oscillations before balance allows the pre -creation; Critical damping creates a rapid return to balance, such as shock absorber in the car; And underscision causes oscillation to decrease over time. A more viscous medium, such as water, creates more friction.

Harmonious movement has many applications in everyday life. Any type of oscillating system - whether it is a pendulum for an hour, a spring from the car suspension system or the engine flywheel rotation - is subject to the form of muted oscillation. For example, the knowledge of friction force that causes damping allows you to calculate the driving force necessary to maintain a constant oscillation rate in the harmonic SYstool. There are also music applications; For example, knowing the length of the guitar chain provides the method of calculating the speed of oscillation when the driving force is given and therefore the frequency of the notes played.
