Okay, so I wasn't away for that long, but it felt like millennia. I haven't really been anywhere, it's just that I realized that I had about two weeks of physics and chemistry work that I haven't even started, so I got to it over the last few days. It wasn't really complicated stuff, as it was just an introduction to both the subjects which mainly meant mathematics, atomic theory and scientific method and measurements revision; easy stuff. On the subject of beginner physics, I bring you my newest comic.

For those of you who don't know the Σ symbol means sum of and the F means forces. When something is not moving, the sum of all forces acting upon it are not netting any movement in any direction, so ΣF=0. So the comic is saying that the sum of forces (choosing between the cake and the ice cream) acting of the little fatty is equaling zero. Funny, right?
That's enough of that, I now come to last posts' winner; Burger! Burger correctly stated the venturi effect in regards to my drawing in my last post. A quick explanation about the effect is this; when a substance is traveling at a faster speed, it is at a lower pressure and the venturi tube (as illustrated) demonstrates this. When a non-compressible fluid is traveling through a pipe of a particular size at a particular rate and then subjected to a narrowing of the pipe, the velocity of the liquid must increase to maintain the same rate of flow. As a result of this increase in speed, there is a notable decrease in pressure of the fluid, as is evident in the difference in levels of the fluid on the vertical pipes.
As promised, I drew a picture just for Burger. I apologize for not doing anything more intricate, I really could not think of what to do. Anyway, I hope you like it!

I think it's time to get back into physics for a little while before I get some sleep. Thanks again for reading!
