Pendulum Investigation: Results by Rachel Jordan https://padlet.com/Room_1606/p5wv1c9r3l8u235r When I made the pendulum (heavier/higher/longer), the pendulum swung (a lot/a little) (faster/slower/the same). en-us 2020-09-02 20:32:40 UTC 2024-12-04 10:29:03 UTC hello@padlet.com Kelsey https://padlet.com/Room_1606/p5wv1c9r3l8u235r/wish/799928741 I noticed that...]]> 2020-10-03 17:44:04 UTC https://padlet.com/Room_1606/p5wv1c9r3l8u235r/wish/799928741 Beth https://padlet.com/Room_1606/p5wv1c9r3l8u235r/wish/799929608 Heavier seems to swing slower]]> 2020-10-03 17:45:10 UTC https://padlet.com/Room_1606/p5wv1c9r3l8u235r/wish/799929608 Marianne https://padlet.com/Room_1606/p5wv1c9r3l8u235r/wish/799930998 I swung the pendulum using 1 earing, then 2, then 3 for 20 seconds and each time it oscillated 18 times. So, in my investigation, it appears that the weight does not affect number of oscillations. However, I will wonder, what if I put even more weight on. These earings are not that heavy.]]> 2020-10-03 17:47:04 UTC https://padlet.com/Room_1606/p5wv1c9r3l8u235r/wish/799930998 The shorter pendulum swung 9 times and the longer one 7 in a 10 sec trial https://padlet.com/Room_1606/p5wv1c9r3l8u235r/wish/799932215 2020-10-03 17:48:38 UTC https://padlet.com/Room_1606/p5wv1c9r3l8u235r/wish/799932215 Gwen https://padlet.com/Room_1606/p5wv1c9r3l8u235r/wish/799932397 I noticed that when I added more weight to the die that it swung at a slower rate.]]> 2020-10-03 17:48:54 UTC https://padlet.com/Room_1606/p5wv1c9r3l8u235r/wish/799932397 Yes when I made the pendulum shorter it increased cycles I tested this multiple times and the different lengths and it was consistent. mezac1 https://padlet.com/Room_1606/p5wv1c9r3l8u235r/wish/799932427 2020-10-03 17:48:56 UTC https://padlet.com/Room_1606/p5wv1c9r3l8u235r/wish/799932427 Fred festes4 https://padlet.com/Room_1606/p5wv1c9r3l8u235r/wish/799932428 Changing the release point didn't seem to make a difference, at least that I could detect.  Tried various angles.  When I went above the level of the table, that started introducing erratic motion.

This did not impact the rate of swing. lindsay_jacobson1 https://padlet.com/Room_1606/p5wv1c9r3l8u235r/wish/799932690 2020-10-03 17:49:19 UTC https://padlet.com/Room_1606/p5wv1c9r3l8u235r/wish/799932690 Anna abatalao https://padlet.com/Room_1606/p5wv1c9r3l8u235r/wish/799932751 65 swings per minute whether released from a higher point or a lower point.  Noticed that swing height and distance from center decreased with each swing over time...]]> 2020-10-03 17:49:24 UTC https://padlet.com/Room_1606/p5wv1c9r3l8u235r/wish/799932751 Lindsay https://padlet.com/Room_1606/p5wv1c9r3l8u235r/wish/799933017 Changing the release point of the pendulum did not affect the number of swings.  However I did notice that the movement of the pendulum swung wide and then started to slow down.
No matter the release point I had around 58 swings per minute.]]> 2020-10-03 17:49:45 UTC https://padlet.com/Room_1606/p5wv1c9r3l8u235r/wish/799933017 No. I repeated the test from two different drop point, each for five times and they all had 13 cycles mezac1 https://padlet.com/Room_1606/p5wv1c9r3l8u235r/wish/799933097 2020-10-03 17:49:52 UTC https://padlet.com/Room_1606/p5wv1c9r3l8u235r/wish/799933097 Charles https://padlet.com/Room_1606/p5wv1c9r3l8u235r/wish/799933191 No matter how high I started the pendulum, it swung back and forth the same number of times.  I kept trying this over and over thinking that I may have miscounted.  I'm happy to see that others had the same experience.  My pendulum consistently swung back and forth 8 times no matter how high I started the release. (10 second time)

As I tried to change the weight it made it difficult to swing my pendulum effectively. I had lots of mistrials. This could be an engineering lesson too. mlmatsuda https://padlet.com/Room_1606/p5wv1c9r3l8u235r/wish/799934271 2020-10-03 17:51:30 UTC https://padlet.com/Room_1606/p5wv1c9r3l8u235r/wish/799934271 Amy jefferson213 https://padlet.com/Room_1606/p5wv1c9r3l8u235r/wish/799934320 As i shortened the lengths of the string, it swung faster.

The lighter the pendulum, the more swings it made.
