It is Monday, February 23, 2009. After just getting back from a relaxing weekend I am not yet ready to be back in school again. Who ever is though? I was walking down the hall to my physics class in room 019, with Mr. Manning, thinking to myself if I had finished everything that was needed to be done for today’s class. I walked into the room and at once saw that there were half sheets of paper on the front lab table, which of coarse meant there would be a graded home work check. Just then I remembered that I had not finished all of my homework and became really bummed out. So I took one of the half sheets and took my seat waiting to start. After we had all finished copying our answers onto the half sheets, we handed them in and then started to go over the answers as a class. Going over the answers really cleared things up for me, and I understood how to do those kinds of problems. After we finished going over the homework, Mr. Manning went to the back of the room, where a model rollercoaster sat, and brought it to the front of the room. He then told us to write a prediction sentence saying weather or not it will loose any of its energy when the car goes around the loop. After this, we all wrote down the equation, and plugged everything we already knew into it. We found the mass to be .096 kg, and the height to be .957 m. after recording all the data we knew, Mr. Manning hooked up a censored that we would use to find the time from start to end. it took a few tries to get it right because whenever we would let the car go, something would be wrong causing us to redo it. Just then the bell rang and it was time to move on to the next part of the day.
