Today, we had a real life scenario for physics. We had to recreate an action movie car crash scene. My group got scenario #1. We had one car going one way and another, faster car, going perpendicular do it so they would go boom! If they don't collide, then we fail. Our slow car took 17:19secs to go 2meters. The faster car was took 10:30secs per two meters. One car always had to be on the table and we could only use on car at a time. The only time we could have both cars going at the same time was when we were doing it for real. My group had to start the slow car, which was positioned two meters away from the point of impact, and at 12seconds, we had to start the faster car. Our group had the best crash! Mr. Battaglia said that some babies died in that crash!
Where does the bad light goes?
To a prism!!!!!
Have a nice break!

Title
Today we had a white board discussion. Today is like the first time I got a chance to talk because of this new rule of raising our hands to talk. I asked a question to this one kid who was talking about the flat lines on the graph. He said maybe the first was traveling sideways. Since velocity also involves direction, I asked what it would look like on a motion map and a velocity vs. time graph. He didn't really answer but that's okay. We had a quiz... I mean fiesta...today. I'm not very confident in my answer. When finding the slope, I counted like how if the y axis intervals went up by 5s, rise over run be a number divisable by 5 over what ever number. So if the point was 3 points up and 2 points over, I would have gotten 15/2. I don't know if it is right, now, but at the time it seemed like it.

Cartwheels for a Cause
Hola bloggers,
today we finished up a lab we started 5days ago. We have to recreate numerous position and velocity graphs using our bodies, a motion detector, and Dora the Explorer. Once we actually started using our equipment right, we saw that if the slope of the line was positive (moving away from the reference point (reference point was the motion detector)), it was above x axis line. If it was a negative slope, then it was below the x axis line and moving towards the reference point.
Last class I was wondering what it would look like if someone did a cartwheel. Mr. B let us test it out since we finished the lab early. He asked us to predict what it would look like on the graph. I said that it would probably look like if someone was walking except a little more wavering (of the line) because I was the one doing the cartwheel and I can barely walk in a straight line let alone do a motion where I put my hands on the SLIPPERY floor and flip my legs over. My prediction was right (YAY), and me and another girl at my table each did 2 cartwheels, one going towards the motion detector and one moving away from it. The lines on the graph were really...wobbly I guess. I don't have a smart phone (yet, I'm getting one soon!!!!) and wouldn't be able to take a picture to put on here, but I totally would if I could. The lines all looked the same except the lines we spaced out...a lot. It most likely has to do with I'm like...7inch taller and she was wearing jeans. Anyway, we had to make motion graphs for the lab. I didn't get it at first but after doing a few of them, I totally understood it. I'm like the motion graph MASTER now! Until next time,...wait I almost forgot the joke...that would have disappointed you, wouldn't it have?
