### How Does Frequency Change With Damping (Underdamped Harmonic Oscillators) [closed]

I'm studying harmonic oscillators and I'm trying to model a system where both the frequency and amplitude decay over time. This is throwing me off because frequency decay is much less intuitive than ...

### Why does the pet's water bowl overflow?

So when i give the pet fresh water in a stainless steel bowl that i place on a mat according to the attached picture, from $t=0$ the bowl is at rest, the water normally oscillates in the bowl like a ...

### If I have a simple pendulum performing oscillations, whose string is snapped when it is at an extreme position, what will happen?

If I have a simple pendulum performing oscillations, whose string is snapped when it is at an extreme position, will it immediately fall vertically downwards because of gravity or will it continue ...

### "Friction at a contact point", rubber-band experiment

I was working on some practice problems in my book, and the question was to describe all the energy conversions that happens when a person pulls on a rubber band and hits it on a board (any type of ...

### Foucault pendulum with General Relativity

It is well-known that the plane of the swing of a Foucault pendulum exhibits parallel transport (wrt to the Levi-Civita connection) of a round sphere. Seeing as Einstein's relativity theories ...

### Spherical quantum oscillator: Is energy smaller than the potential?

A particle with mass $m$ is inside the spherical quantum well $V(r)$: V(r)= \begin{cases} -V_0, & \text{if}\ r<a \\ 0, & \text{otherwise} \end{cases} \...

### What are standing waves?

What are standing waves? I'm new to wave mechanics and I don't seem to be able to understand why standing waves form. My specific doubt is how do they form and why do they form? Some intuition might ...

### Why we take only the real part of a solution as the actual motion?

I am taking Analytical Mechanics, and in Goldstein's book, chapter 6 (page 241) about linear oscillations, he says the following: "... $\eta_i=Ca_ie^{-i\omega t}$ (6.11) ... It is understood of ...

### Does entanglement rule out oscillating properties?

This will be a very noob question and I am a novice but I just wanted to understand entanglement better. This is just a toy analogy that I thought of and again, I don’t know the intricate details of ...

### Can motion be oscillatory but not periodic?

The equation of motion of a particle is $x = A \, \mathrm{cos}\left[(\alpha t)^2\right]$. What type of motion is it? The answer to this question in my textbook was: "Oscillatory but not periodic&...

### Movement of a mass on a spring in damped SHM

Suppose a ball is connected to a spring attached to a wall, and they are in space, i.e. assume no gravity. The ball is put into a fluid with Stoke's drag and oscillates backwards and forwards relative ...

### How does time period change with damping in oscillations?

Does time period increase or decrease with an increase in damping? I've had contradicting answers. My teacher has told me that time period increases with damping. It does make sense in a way because ...
