If you are aware of an interesting new academic paper (that has been published in a peer-reviewed journal or has appeared on the arXiv), a conference talk (at an official professional scientific meeting), an external blog post (by a professional scientist) or a news item (in the mainstream news media), which you think might make an interesting topic for an FQXi blog post, then please contact us at forums@fqxi.org with a link to the original source and a sentence about why you think that the work is worthy of discussion. Please note that we receive many such suggestions and while we endeavour to respond to them, we may not be able to reply to all suggestions.

Please also note that we do not accept unsolicited posts and we cannot review, or open new threads for, unsolicited articles or papers. Requests to review or post such materials will not be answered. If you have your own novel physics theory or model, which you would like to post for further discussion among then FQXi community, then please add them directly to the "Alternative Models of Reality" thread, or to the "Alternative Models of Cosmology" thread. Thank you.

Video Description

Welcome to Explained! This is a show where we demonstrate physics concepts in fun ways. In this episode we cover the principles behind centripetal force. In the video we lit steel wool on fire and spun it in a circle to showcase the physics behind centripetal motion. Do not attempt the main experiment at home! Thanks for watching!

Video Creator Bio

Our names are Ian Harris and Grant Karolich. We are two graduating seniors from Glenbard West High School. We both took physics AP our senior year and thoroughly enjoyed it. We are looking to continue studying similar subjects as future engineers at University of Illinois at Urbana Champaign. We love being able to combine our knowledge of physics with our passion for filmmaking, and this contest provided us with that opportunity.

Ian and Grant,

Congratulations for a very dynamic video, which was well shot and well edited. Pretty legit for graduating high school seniors! :)

May I make a few suggestions if you ever do an updated version or a follow-up?

1) Around the 1 minute mark, when you state the equations for circular motion, it would have been great for them to appear in overlay over the shot of...

Hey there Ian + Grant!

I just wanted to say that I really enjoyed your video. The editing and pacing were excellent. It was, indeed, a legit explaination of a basic physical force: I gave you 4 stars. I am interested in the real life application of centripedal forces and all I can come up with online is stuff about roller coasters. Can you tell me about some of the applications besides roller coasters and cool light shows ;)

If you have a moment, it would be much appreciated if you could tell us what you think about our video.

Best of luck in the competion guys!

Hey guys,

This is a really neat video. That long exposure photo turned out great!

If you can find the time to watch and rate my video, "The Cool Physics of Refrigeration," before the Friday deadline, it would be greatly appreciated. Thanks!

Your video is very interesting, and I loved it!

My video is A universe in a cup of water, I hope you will like it too.

I wish you success!

Very nice, guys! Your camera work and shot placement are much better than I know how to do. The sparks are an excellent way to visualize what's going on, and the time-lapse shot is truly spectacular. Were you just burning steel wool? That's a physics video in itself...

In terms of the explanation section, I'd caution that it's usually better to find a way to explain something in terms an non-physics viewer can understand. For example, WHY should the acceleration of a circular object be v2/r? It's not immediately intuitive that an object travelling at a constant velocity is accelerating at all, and more particularly, why THIS formula out of all possible dimensionally correct formulas? The viewer should really be able to walk away with an intrinsic intuition for why the object behaves the way it does. I suppose a really easy way to at least show that there are forces at work, in this case, is just to encourage the audience to try the tennis-ball themselves, and feel how they have to keep changing the direction in which their arm is exerting a force. Make it something undeniable.

Anyways, hope you guys do well! My videos are the "A Capella Science" ones if you haven't rated them yet :)
