Homework Statement Hi, I'm currently trying out a practical problem where I'm trying to calculate the energy present in an inflated balloon, as well as what happens to that energy once the air is let out from inside the balloon. The balloon is attached to a car, so that as the air escapes it...

Ah I see. Thanks!

Well I wasn't really aware of that... Still, don't most balloons have roughly the same shape? And how would changing the shape (hypothetically) affect the distance of the car?

Hi, regarding your suggestion, there are a few things to note. Firstly, what do you mean by shield? If you mean any object which physically blocks the balloon from the air, well attaching it to the car would add on to the mass, and even if it did manage to decrease the air resistance, the added...

Well the shape is pretty much that of a typical balloon... it's an ovoid(3D oval shape). It's not a perfect sphere, at least.

Homework Statement Hi, this isn't so much a specific question, but rather a project which I'm embarking on. As part of my coursework, I'm required to take up and work on a Physics project, and I've chosen a problem fro the 2011 IYPT. The problem statement goes like this: Build a model car...

Hi there! I'm a High School student from Singapore who's really interested in Physics. I find Physics really fascinating, about how it manages to describe the universe and all that, so I'm looking forward to learning more about it! ^^ I can't understand most of the complicated equations yet...
