Blog 6: Soda

For the long Thanksgiving weekend, one of my friends hosted a pool / barbecue party.  It was real fun and everyone enjoyed their time.  We played cards, grilled food, relaxed in the jacuzzi, and some people sang karaoke.  But as usual me and my friends were messing with each other.  They thought it would be funny to shake up my soda while I was not looking and watched me open it.  After it blew up, I realized that it was a explosion reaction.  An explosion reaction's equation, which is the combined mass of all the components' multiplied by its velocity is equal to the mass of the separate components multiplied by their individual velocities.  This means that the soda's momentum which left the can was equal to the can's momentum.  Although this is true, the can looked like it had no momentum.  Since its velocity was in the direction of the ground, its force acted upon the ground, but the ground's mass is so large that it experienced zero acceleration.

The can left me a little wet and a little annoyed, but they got messed up later.

Blog 5: Math Attack

On Sunday I was busy doing homework.  I started pretty late, but I almost finished all of my homework by 11.  All I had left to do was complete my math homework and do this physics blog.  Unfortunately, I spent the whole Saturday night registering for the December SAT.  I thought it would be a quick process, but it took hours on end.  I also had an appointment earlier in the day on Sunday, so I was very tired by the time I am writing this blog.  I tried to lift my devastatingly heavy textbook out of my bag, but it was too heavy and I dropped it on my foot.  I knew that because of my physics homework all of the book's potential energy was converted into kinetic energy which transferred into my foot.  I finally stopped crying and wrote the blog.
