Today we started our bowling forces lab. In this lab Lauren, Keira, and I rolled around various round sports equipment and timed how long it went 8 meters. We rolled each ball slow one time and fast the next time. Lauren rolled every time so we could try to get the same amount of force. I was the timer and Keira was the reckless roll catcher. She made sure that we wouldn't crush the door because we got really close to doing that. Also, every time we rolled a ball we wrote down the weight in Kg of the ball and the time it rolled into a data table.

Today we finished up our rolling. We rolled a bowling ball, a softball, and a big red exercise ball. The bowling ball was extremely heavy so I am expecting to find a lot of N of force that we need to push it 8 meters when we make our calculations. We also started calculating the velocity and acceleration of the balls we rolled so we could start finding the force we needed to roll each ball. I really liked this lab.

Today we did something I am not going to forget. Mrs. Giacomelli said she was going to smash a cinder block on Mr. Simon's belly. She was asking us how to lay the cinder block on Mr. Simon so we hurt him the least. We decided to lay the cinder block on its flat side because it must be sturdiest with its holes on top. We assumed this because when people build with cinder blocks they build the holes on top. Mrs. G then took a sledgehammer and smashed the cinder block on Mr. Simon's belly. We then had to list reasons why Mr. Simon did not have a big hole in his stomach. Three of the reasons include: The force was distributed on his body. The force was partially used to break the cinder blocks. The force wasn't even that great because cinder blocks break easily as they are not built to withstand sudden shock. We also finished our lab after this.

Today we had to turn in our lab. We also talked about the different types of forces that affect an object's motion. These forces are air resistance, friction, gravity, applied force, and normal force. I learned that an example of normal force is when a pencil is on a table the table pushes up. We also used free-body diagrams and diagrammed all of the forces acting on the object. We then had to find out the net force or where and with how much force an object is moving.

Today we finished our study guide for the test on Unit 1 that is coming up soon. We were able to get help from Mrs. Giacomelli which made me feel very relieved because some of the questions where pretty hard. Did you know that static friction is the force that acts upon an object that is not moving? An example of this can be seen when you cannot move a box that is on a rough surface.
Summary: This week was better week than last week, but I still need to work on making my things neater and more organized. I can do this by making my notes neater by always bringing a good, sharpened pencil. I can make my labs neater by writing on a separate sheet of paper if there is not enough room on the lab sheet itself.
