Stars!

Okay well, time for another edition of Steph's AP Physics blog! Yay! I think I'll combine two blogs into one because I don't think either will be very good. Alrighty then. That being said, let's start. Today's topic is: STARS. I love stars and I think they're awesome.

So this weekend, I uploaded a song on my iPod called "Airplanes." I really like the chorus which goes "Can we pretend that airplanes in the night sky are like shooting stars? I could really use a wish right now." I like stars and wishes, so it got me thinking. What are shooting stars? I found out that meteoroids get caught in the atmosphere and burn up as they fall to earth, hence the awesomeness that is a shooting star. Though the name is very inaccurate. The reason they fall to earth is GRAVITY! And the earth's gravitational field! OH MY GOSH! 9.8 m/s^2!!!

The other star I'm going to talk about is a balloon. :] One of my balloons from my birthday is deflating, but still has some helium in it. Right now, it looks super cool because if I were to cut it off the string, it would float in midair! So yeah, the weight (MG!) of the balloon points DOWN! Like ALWAYS! Buttttt, the helium inside the balloon keeps it afloat by evening out the weight just enough so the balloon is in equilibrium! Yay!

Ignore the giant mess that is my room. >.<. But yeah, there you go. It's all floaty (I'm talking about the blue star, in case you didn't know)!

Have a great week everyone. Just a few more! We can make it!
