You're learning hand gestures! Wonderful! Very distracting though and makes it hard to listen to what you're saying - the opposite effect of what "natural hand gestures" are intended to do. Keep practicing! No judgment here! It's an awkward phase of beginning to develop the use of hand gestures. In this beginning phase it's like you're learning a new language and you have a handful of words in your vocabulary and you're consciously thinking about using each one producing a broken clumsy style of speech, while also talking in fluent English. It's like trying to listen to someone while a 2nd person is talking at the same time but in a crude way. It gets easier though over time and I don't mean this as a put down because I went through a phase like this too.

Thank you so much! Just curious; I noticed that between the low and high amplitude, the spring seemed to become almost still (visually) What is that? Is that a phenomenon with a spesific name? Would like to learn more. Is it the same thing that happens when running water looks frozen or car rims look still when rotating? Again, thanks!

@zhelyo_physics Месяц назад
very interesting. Such an excellent question! Let me explain it intuitively. Imagine you are pushing a pendulum with your hands and a pendulum attached to the ceiling. If you are pushing at the exact time the pendulum reaches you, its amplitude will increase to a maximum and the pendulum will experience greatest energy transfer. If you hit a different frequency when your hands are completely out of sync with the pendulum, no energy will be transferred as your hands will just be pushing the air and not the pendulum. This is essentially what we are seeing. I hope this makes sense! : )

Excellent explanation sir.I have a question.Let's say a tuning fork has a natural frequency of 250 Hz and we hit it against the table, does that mean a tuning fork is oscillating back and forth 250 times a second or a tuning fork is creating a sound wave that has a frequency of 250 Hz or both of them?

I've read that resonance occurs even if driving frequency isn't equal to the natural frequency. It is for the case when driving frequency is integral multiple of natural frequency. Why do u say about this sir??

So an object can typically vibrate in multiple "modes" of resonance. Totally true.

correct! Sometimes there are more resonant frequency later on but for A Level Physics if that's the course you are doing this is typically not required to know. Hope this is helpful!

So how do we measure these frequencies… Most importantly how does one measure specifically the frequency of a static object to when the object is disturbed from a specific location?
@zhelyo_physics
@zhelyo_physics Год назад
So we apply a force and measure the time period of the oscillation with respect to the point. Typically we measure 10,20T and then divide by the number to get an average. Afterwards f=1/T
@shayanelhoque6929

So if I were to take 2 mounted tuning fork and tap one of them, would both vibrate at the same frequency regardless of the other tuning fork's size?

Does natural frequency change if you apply more tension or force though?
@zhelyo_physics
@zhelyo_physics Год назад
Depends on the specific situation. Generally objects tend to oscillate at an unchanged frequency once the forced that caused the oscillation is removed.
@BM-vl6bo
@BM-vl6bo Год назад
@@zhelyo_physics would the frequency technically be higher in the first second after the force is applied as to a couple seconds after the force is taken off? Do we measure natural freq immediately after the force is taken off or do we wait a couple seconds ?
@zhelyo_physics
@zhelyo_physics Год назад
after the force is taken off the amplitude decreases but the time period remains constant (in most systems, if it's a pendulum only for small angles). I recommend checking this video out for a good understanding of resonance: ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-UBKGsWe4Bmg.html Good luck! : )

Are there formulas to calcuate the natural frequency of various materials? (Glass, steel, copper, etc.) Presumably the variables would include diameter and length e.g. a copper bar 6 feet in length and 1" in diameter or a steel tube 3 feet in length with a 2" internal diameter
@zhelyo_physics
@zhelyo_physics Год назад
Excellent question! They are different in different situations. I discuss this a little bit more in depth here: ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-UBKGsWe4Bmg.html For a simple oscillating mass on a spring it is sqrt(k/m) but different in each situation. Typically it is simply measured for an object. Hope this helps!
