Clear as it flows down further you may be able to hear the wobble motion I will hold my
Microphone close up unit very high frequency already that you hear it quite amazing isn’t it when you look at it wobbling frequently increases quite rapidly look how the as initial motion slows down
Out the frequency of the wobble goes up uh… malcolm’s but very difficult beetle physics right there
If you take a tennis ball this is a super bowl and deposits but but but school student involvement thank you then you also get some kind of a periodic motion whereby again the frequency increases just like the case of the or that this guy and the breakfast plate he was an object that is floating inadequate in water and if pushed up a little far terrain let it go wobbles and there is a very unique frequency that you will be able to calculate it’ll three very unique period of one complete all solution as these object goes up and down even win steady wins can generate periodic or almost periodic motions which all of you have experienced the walkout sites Israeli and your hair goes like this mail doesn’t go flap like this always has this tendency just like Affleck does the same thing by generate wind here and I have here are some of them you’ll see that these went doesn’t make the aluminum driscoll straight-out booked global says certain period to that after work if you want to have some fun what is more fun writing your own walking that’s a periodic motions falling in love can be a periodic event no don’t do it too often because that most of you know quite exhausting the motion of electrons molecules periodic and also look toward the motion of the moon the planets and stars periodic oscillatory silent is a beautiful example I produce some could do sound by also made in my vacal chords I put in which they are by pressure waves my vocal chords push on the air suck on the air push on the air which prosuced a pressure wave in the pressure wave propagates out intellectual hole reaches you he had run but you don’t start to moved back and forth and you your brains tell you that you here and shops I have your tuning fork which is designed so that if I give it a hips at the prongs moved when the fifty six times per second recall that two hundred fifty six hurts Roberts is one also nation seconds middle newland national weighty not generate and we will killer stared offering travel buddy air retrieved from and you can start to shake this is a higher frequency four hundred forty hurts
