Check out this video on waves dont look to hard you might go dizzy Really look at the motion of the balls,notice the differnt length of the string attached..
This is pretty darn cool. I was wondering is the setup making a waves at all times because at certain points it looks as if it is not synchronized enough to be considered a wave? This could just because it is moving faster and my eyes aare playing tricks on me though.
That's interesting how they all move in a single line at one point. I remember something like that from high school physics when we covered wave characteristics, but its pretty nifty to see in action.
I watched this video twice. It looks so cool but if all the balls start at the same time, how come they change and make the wave partern? is the length of the strings got to do with the speed the balls swing??
Tulsi, from my perspective after watching the video, the length of the panels covering the strings of each ball has to do with the wave pattern and speed of the balls swing. The one area i was confused about was if the music accomanying the video have an effect on the wave pattern of the balls. Is anything coming in contact with the panels to send vibrations down the string in order to change the direction or speed of the swing?
Meagan, I agree that the the panelling has to do witht he speed but I think it is the length of the string as well. When we did the harmonic wave lab we saw that the pendulum completion time depended on the length of the string. It makes senses that eventually the objects would wave because they all have different string lengths making them have different pendulum times. but does the device as a whole have a pendulum period? It seems to come to a straight line then repeat again.
This is what we learned about last time in lab. All the pendulums have a different length. The shorter perdulums will swing faster than the longer pendulums. These guys just timed it and arranged them in a really cool way! Lori Waite
This was cool to watch. It was interesting how the balls would be moving in a wave like motion and then look totally unorganized and unsynchronized and then jump back into the wave motion again.
I watched this video two times, once without any sound. The music alters the perception to me but it reminds me of the last lab. It also reminded me of this shoe commercial, http://youtu.be/s8soN75h5l0
The coolest part in the video was seeing how the balls were out of sync and then were able to get back in sync and begin to form the wave shape again. Really cool video
All has to do with the length of strings holding the balls which affects the rate of speed of the pendulums. Cool seeing the wave form more crests, and the frequency increase then decrease again. Thanks! -Hannah Roddy

ReplyDeleteSo I watched this video two times in a row:) This is really cool. It's amazing to learn how physics impacts so many aspects of our lives.
ReplyDeleteI agree with Kyle there are points when the balls seem to be out of synch. Is that the case our is that an optical illusion?

This is really cool. Interesting how (for the most part) they are in sync the whole time.

Amazing video of a pendulum.The length of the string is a major factor for the speed of the pendulum.Loved how they timed the pool balls perfectly.
ReplyDeleteWow that was a cool video! At some points the balls were moving in a way that they looked similar to a DNA double helix rotating!

ReplyDeleteI enjoyed watching the video. It was cool to see how the balls were able to come back in sync and act like a wave.

Very cool video. Thanks for sharing!
ReplyDeleteTo Meagan,
ReplyDeleteOh ok thanks... that made sense when I watched the video again

Great video! It was really awesome when they looked to be totally in sync.
