Скачать или смотреть natural frequency pendulum and springs a science with bobert video short

(video of pendulum) (natural (i.e. resonant) frequency)
(voice…natural frequency?? What’s that?) I know it’s weird but EVERY object has at least one natural frequency. A person swinging on a swing is like a pendulum. It does not matter how far back you pull a pendulum, a pendulum always oscillates at the same frequency…just like the swing, the only way you can change the resonant frequency of a pendulum is to change the length of the pendulum (video) (darth vader voice: or go to moon!) Yah, that’s right.

(video of spring) a hanging spring also has one natural frequency……it does not matter how far the spring is pulled down, it always oscillates at the same frequency. so springs, pendulums and swings are examples of objects that when you get them to oscillate, they all have only ONE natural frequency.
