The video is in the post after this, but read this first...
Alright, I know I talked about football last week, but I got to say that this week was much better. I had a run! yay me! Unfotunately, my mass and velocity were too small, so my collision with the defender ending up in my momentum being redirected back.
Okay, on to the real part of my blog. The awesomest example of physics I've seen in the past month was in this video from Saturday Night Live. Basically this dude is throwing things on the ground, and smashing them. When the object gets thrown on the ground, the conservation of energy means that all the peices of the smashed object and the energy lost to the collision and flying peices remains constant. The same holds true for momnetum, but since the ground doesn't move, the peices just fly back with the same momentum. Lots of physics happens in throwing stuff on the ground. Also, this video hasa some language, but nothing you wouldn't here in Doc's class. Go steelers!
oh, and you can't trust the system.
