Physics Blog 2 "No Break From School"


When I start talking outside of class about a topic that was discussed in class, it has officially become ingrained in my mind. Last Thursday, my friend and I were walking back to school after going to pick up lunch. Amazingly we started talking about physics and how we had to write blogs for class. :D While we continued to talk, I was watching the cars on the road speeding by. As the cars sped by, I could hear their engines, which interestingly reminded me about acceleration. The cars passing us by all had different accelerations. I noticed that some cars moved forward faster than others and the gap between the slow cars and the fast cars became bigger and bigger. The cars that created the big gaps between themselves and the slower cars had larger accelerations, while the cars that were left behind had smaller accelerations. If the acceleration of the faster cars were represented by a graph, it would look like a constant positive horizontal line. Although it would be hard for a driver to accelerate at a constant rate, the cars that passed us on the road seemed to have a constant acceleration.

Physics Blog 1 "My Intriguing Morning"


One morning, I arrived at school and sat down at senior benches. I did some homework and then when the bell rang, I got up and went to homeroom. As I walked to homeroom, my velocity for the most part was constant, but then I arrived in homeroom. My velocity for the entire 5 minutes of homeroom was zero. Then when homeroom finished, I walked to class but this time, my velocity was slower because I did not have to walk very far for my next class. After finishing class, I walked back to senior benches and sat down. This is when I realized that even though I took different paths from and to senior benches my displacement was zero. I ended up in the same exact place I sat down in earlier that morning. If displacement instead of distance were used to describe how far I traveled in a day, it would seem as if I did not go to school and instead slept in. :D
