Good with physics?

[christiankills 10+ year member]

I have a physics project due soon. I have to take a picture of something dealing with physics in the world, and I have to write a 250 word essay on why it deals with physics.

What I plan on taking a picture of is my subwoofers vibrating, get some really heavy bass song, and get a good big vibration.

Any ideas on how this deals with physics? I plan on mentioning conservation of momentum.

Maybe explain the physics behind how the cone of the electrodynamic transducer (the subwoofer) oscillating back and forth a certain number of cycles per second (frequency, expressed in hertz) creates sound through compression and rarefaction of the air? Or the forces involved with causing the cone to move; i.e the reaction between the static magnetic field (the magnet, topplate, bottom plate and pole piece) and the electromagnetic field created by the AC current flowing through the voice coil causes the cone to move? The physics behind how the enclosure affects the subwoofer? The physics behind a ported enclosure (helmholtz resonantor)? Theile and Smalls analysis of an electrodynamic transducer....which later became known as the Theile-Small parameters?

Seriously, there are hundreds of topics and angles you could take with this that involve phyics. Everything to do with speakers and subwoofers in general revolves solely around physics.

250 words?

that's less than a page

this is assignment should be easy as hell

Shouldn't be hard at all.

even air movement is physics. physics is the reason everything is the way it is. 250 can cover just about anything. even the power going to the sub, V=IR is physics. what level is this? High school? shouldn't be a hrad thing to write.

Man thats easy, take college level engineering physics.

Physics is everywhere man. You could take a picture of the sky and write 250 words about that. But for your subwoofer pic, talk about oscilation, magnetic fields surrounding the coils, resonance frequency, the list goes on..........

By the way what school do you go to?

Physics involves almost anything you think of. Typing this thread can relate to physics. You could go in depth about frequency and hertz and things of that nature if you wanted to deal with your subwoofers and whatnot.

Actually, your teacher would be quite proud if you were to do that probably. Talk about the quantum mechanics of oxygen and nitrogen and how the difference in energy between different electronic levels within each causes light of certain frequencies to be absorbed - transmitting other colors...hence why the sky is blue //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif

or did you know that every single bubble turns black right before it pops due to surface tension? more physics... and yeah, try 2 semesters of college engineering physics. i can talk about this crap til you go crosseyed.

That's easy as hell man. Just copy what squeak said into a Word doc, add a few transitions and presto! You have a paper!

Sorry about th elong wait for the reply.

Squeak.. you truely deserve that mod spot. haha.

I never knew there would be this much physics in subwoofers, I figured a couple of things, but you guys have named a lot.

thank you for all of your responses. My teacher really liked my idea, thought it was creative //content.invisioncic.com/y282845/emoticons/biggrin.gif.d71a5d36fcbab170f2364c9f2e3946cb.gif

I go to alonso high.

wow, i wish i was in your physics class....

i have to design a rollercoaster, with a minimum of 5 corners, 2 loops and 3 hills, calculate the accelleration, decelleration, force needed to get roller coaster up hill, cooefficient of friction, G-forces all around, (ex: bottom of hills, tops of hills, corners) exact metric demensions, and then write a 7 page analysis on it.

but that's highschool physics for you.

My final is gonna be to take a picture about physics and submit it into this nationwide pitcure physics contest

Im thinkin something with a port and a cloth, with the wavyness and whatnot with the speaker in the background
