Simple harmonic motion and frequency

AI Thread Summary
In the discussion about simple harmonic motion and frequency, several statements regarding the effects of mass and amplitude on frequency were evaluated. It was concluded that quadrupling the mass does not halve the frequency, and doubling the spring constant does not double the frequency. Additionally, tripling the amplitude does not sextuple the frequency, and doubling the amplitude does not affect the period. The confusion arose around the relationship between amplitude and frequency, emphasizing that frequency remains constant regardless of amplitude changes. Understanding these principles is crucial for solving problems related to simple harmonic oscillators.

Homework Statement


Consider a simple harmonic oscillator made of a mass sliding on a frictionless surface, and attached to a massless linear spring. Which of the following statements are true/false?
True False Quadrupling the mass will halve the frequency.
True False Doubling the spring constant will double the frequency.
True False Tripling the amplitude will sextuple the frequency.
True False Doubling the amplitude will not change the period.
True False Doubling the amplitude will halve the frequency.



Homework Equations



f = (1/ [2pi/sqrt(k/m)])

Vmax = A(2pi/T)

Vmax = A(2pif)

The Attempt at a Solution



using simple numbers I got the answers in this order

True
False
False
False
True

My numbers work out, but I'm wrong...
Any suggestions?
Thanks

Does frequency depend on amplitude?
 
Ok... So doubling the amplitude doesn't effect the frequency, but I still can't get this question right...

I'm so confused
 
Three of those questions refer to amplitude. Check each one.

Thread 'Struggling to make relation between elastic force and height'

Hello guys this is what I tried so far. I used the UTS to calculate the force it needs when the rope tears. My idea was to make a relationship/ function that would give me the force depending on height. Yeah i couldnt find a way to solve it. I also thought about how I could use hooks law (how it was given to me in my script) with the thought of instead of having two part of a rope id have one singular rope from the middle to the top where I could find the difference in height. But the...

TL;DR Summary: I would like to know the voltmeter readings on the two resistors separately in the picture in the following cases , When one of the keys is closed When both of them are opened (Knowing that the battery has negligible internal resistance) My thoughts for the first case , one of them must be 12 volt while the other is 0 The second case we'll I think both voltmeter readings should be 12 volt since they are both parallel to the battery and they involve the key within what the...
