This is a picture of me at China Walls. If you can't tell by my face, I'm not very happy. I was trying to climb back up, but the sets were coming in fast, and the rocks were very slippery. After a while, I became very frustrated and waited to climb up the other rocks. This is kind of like how I feel about Physics. It's a bit frustrating for me, as I find the tests really difficult. There are a lot of concepts and equations, and I usually panic during the tests, resulting in not-so-good grades. Also, the homework is sometimes difficult as there are many steps to all the problems. I would like it more if we went over all the problems in depth in class, but I know that time doesn't always allow that. I like the labs a lot, and I have an easier time understanding the concepts, I'm not sure why. I think to improve in the subsequent quarters, I should do more practice problems and come in for help right when I start to get confused. This can prevent my frustration on my tests and quizzes, and ultimately would help me get a better grade. Thankfully, physics is very interesting, and I at least am able to stay awake in class, and when I'm doing my assignments :) Hopefully, by making these adjustments, I will be able to raise my physics grade, and won't be as frustrated as I was that day at China's.Sunday, October 19, 2008

Friction and Force
This weekend, my family went to dinner at a Japanese Restaurant. After everyone ate the food, my brother and cousins were sliding the shoyu container across the table to each other while we waited for the adults to finish talking. I then realized that this could be applied to what we we're learning in physics! The shoyu container had forces working on it while in motion. The gravitational force of its weight and the normal force pushing upward worked while the force of the hand pushing the container caused it to move. Also, the friction from the table kept the shoyu container in equilibrium. I took this video of my brother sliding the container toward the camera, demonstrating Newton's First and Second Laws.
