Amplitude is related to energy, and amplitude is a physical quantity indicating the strength of vibration. For the same object, the greater the energy, the greater the amplitude.

Amplitude refers to the maximum value that can be reached by the physical quantity of vibration, usually represented by a. In mechanical vibration, amplitude is the absolute value of the maximum displacement from the equilibrium position when the object vibrates, and amplitude is equal to the maximum displacement in numerical value. The amplitude is a scalar, expressed in meters or centimeters. Amplitude describes the amplitude and intensity of vibration of an object.

Amplitude is the characteristic physical quantity of vibration, and some physical quantities related to vibration are as follows:

1 and period

The time required for an object to complete a complete vibration is period t, and the unit is seconds. Period is a physical quantity representing the vibration speed of a particle. The longer the period, the slower the vibration.

2. Frequency

The number of times the vibrating particles complete the total vibration in one second is called the vibration frequency, and the unit is hertz. Frequency is also a physical quantity representing the vibration speed of particles. The greater the frequency, the faster the vibration. The relationship between period and frequency or its unit relationship is 1hz = 1s (- 1). The vibration frequency (period) of simple harmonic vibration is determined by the nature of the vibrating object itself, so it is also called natural frequency (natural period).

3. Complete vibration

After full vibration, the vibration state of the vibrating particles returns to the original state.
