Homework Statement Find the average spring constant (k) of a water-balloon launcher, and use that to find the distance to pull back the launcher and launch a balloon of a certain weight a certain distance. I'm at the "finding k" part. Diagram attached. Known: Weight of balloon (Fw, N), mass...

Haha, I know. I just saw it and thought that it could be a representation with macro objects with fewer wavelike tendencies. =) Maybe it's because it was an old book...

In c on the first set, there's a ray that you forgot to trace back. :) Always put directional arrows, as gc2004 has said. You usually only need two rays, but if you want to check to make sure you've got it right, you can use three. Especially if that's what the textbook said to do. :D A...

Oh! I found a really cool analogy of this the other day. Imagine that you're blindfolded in a room, and you have to stay in one location and find a chair. All you have is a baseball to judge distances. So you throw the ball around a little bit (assume that it can come back to you), and you...

I'm not thinking of an entire piano, with pedals and everything. More like an afternoon project than a full invention. :) I only used the word "piano" because that's kind of what it would look like, just with no black keys. The one I was planning on making, the desktop-model, would have...

I was thinking that it's possible to make a sort of "piano" using solenoids. If you had a spring to reset it, and the "keys" of the "piano" activated simple contact switches, it could be done, right? It wouldn't be a terrible strain on the batteries if the contact were as short as pressing...

Absolute Zero is a tricky concept. You can get close, but never there. It's asymptotic and theoretical. ...But if you -could-, then I don't see why gravity would affect it.

When determining what is a lot, think, "what does the meter go up to?" Think about the scale of it. (One Becquerel (Bq) is 60 DPM, by the way.) Really, it matters how big the sample is. If you've got a massive DPM count, then either the sample is huge or you're dealing with an unstable...

I really like LURCH's examples. Kudos. ^^ That could be in a textbook. Here's an elaboration, just because I can't let it go unsaid. The exact location of an electron isn't known. It's more like a cloud of probability. It's "probably" in a certain range. Electrons have more wave...

One of the best things that you could do if you are strapped for ideas is look around at other physics games. (I'm not saying to plagiarize them, I'm just saying that you might be inspired by something you see.) Handy Links: http://www.kongregate.com/games/Zyzic/n3wton...
