      That's happened before! Different parts of the body have different frequencies. My physics teacher told me about a situation in which the blades of a helicopter were rotating at the same natural frequency of the pilot's eyeballs. He temporarily went blind and crashed the helicopter. It's something that engineers have to consider from now on. Also the natural frequency of the eyeballs for example differ from person to person

    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
      @zhelyo_physics  4 місяці тому +1

      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! : )

    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.

    • @zhelyo_physics
      @zhelyo_physics  2 роки тому +1

      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

      Depends on the specific situation. Generally objects tend to oscillate at an unchanged frequency once the forced that caused the oscillation is removed.

      @@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  Рік тому +1

      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: ua-cam.com/video/UBKGsWe4Bmg/v-deo.html Good luck! : )

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