### Difference between Oscillatory motion and vibratory motion

What is the difference between oscillatory motion and vibratory motion. I have read in my book that "If the amplitude of oscillatory motion is extremely small,the motion is called vibratory motion". ...

### What is the difference between “monochromatic” and “impulse” force?

In a paper I am reading (linked below), the following is stated: The transient motions of the sphere and the gas bubble in the elastic, incompressible, inviscous medium are investigated in response ...

### What is the difference between Non-harmonic oscillation, Anharmonic oscillation and Complex harmonic oscillation?

I am just wondering if the words Non-harmonic oscillation, Anharmonic oscillation and Complex harmonic oscillation mean the same thing. If not what exactly is the difference between them? Since the ...

### What is radial oscillation and how is it measured?

In the context of the Earth orbiting the sun, the question of the problem is "If the radial oscillation has a higher frequency than the time it takes the Earth to orbit the sun, will the aphelion ...

### Significance of the word 'linear' in linear harmonic oscillator

In my book Advanced Acoustics there is a line- A particle undergoing SHM is called a linear harmonic oscillator If I say that the word linear is used for the 2 reasons- The motion of the particle ...

### Synchronized oscillations

Please I'm a little confused about this. When are oscillations said to be synchronized? Is it because they vibrate at the same frequency or because they are in phase? Got a question with both options.

### What is the meaning of “kay effective” $k_{\rm eff}$ in SHM?

I am really confused studying for my Physics lectures on oscillations, namely Simple Harmonic Motion. You see, my Professor introduced the topic: when he solved some examples, I noticed that when ...

### Difference between harmonic motion and simple harmonic motion?

The name simple harmonic motion suggests that its the simple version of "harmonic motion". Does harmonic motion exist and if so is there a difference between these 2 terms?

### Difference between “Periodic motion” and “Oscillating Motion”

So far I know one of them is a special case of the other: The Oscillating motion being the special case of Periodic motion. But I don't know the precise "Kinematical definition" of each one. I mean ...

### What is the difference between note, tone and mode?

What is the difference between note, tone and mode? In physics, wave mechanics and vibration specifically, do the terms note, tone and mode mean the same thing or do they refer to difference things?

### SHM with acceleration at mean position

Suppose we have an equation of motion as $$\frac{d^2x}{dt^2} = -kx + c,$$ then can it be called a SHM? Since acceleration is still proportional to displacement. But then, how will we define the mean ...

### What is a mode?

The word mode pops up in many fields of physics, yet I can't remember ever encountering a simple but precise definition. After having searched fruitlessly on this site as well, I feel that even ...

### What is a full cycle in damped oscillation?

Maybe it seems a dumb question, but I can't understand what the cycle in a damped oscillation is? Let's take an example: In harmonic motion, one cycle is the smallest distinguishable part of wave ...

### What does multi-periodicity mean in stellar pulsations?

How can there exist multi-periodicity in stellar pulsations? http://www.kitp.ucsb.edu/sites/default/files/kitp/preprints/moskalik2.pdf How can one visualize a multi-periodic pulsation or oscillation?

### Difference between harmonic oscillator & coupled oscillators

Coupling, according to wiki, is the condition of two systems when they interact with each other. Now, I came across the terms harmonic oscillator and coupled oscillators. Now,what is the difference ...

### How do you define the resonance frequency of a forced damped oscillator?

Consider a forced, damped harmonic oscillator $$\ddot{\phi} + 2\beta \dot{\phi} + \omega_0^2 \phi = j(t) \, .\tag{1}$$ If I pick a sinusoidal driving force $j(t) = A \cos(\Omega t)$, I find \phi(...
