1st Quarter Review Journal

For the first quarter at least, Physics seems to be better for me than Chemistry ever was. I decided to choose a picture of an eraser and corrective pen because I know that I need to make mistakes and work hard in Physics before I can master the concepts and succeed. Physics is a very interesting class, and the labs that we do are at the same time fun and applicable to learning the laws of nature. I also enjoy the Physics videos that we watch like Mythbusters and the Japanese game shows, because they show how Physics can be integrated into the real world in new and interesting ways. Though I find Physics interesting, I sometimes have trouble working with its equations; but I know that if I keep erasing and correcting, I will understand them in the end.

Position Graphs

This week, my family bought a new wireless mouse after our old one broke. Though I'm not exactly sure how a wireless mouse works, I think that it is based on the same technology that we used in our position graph lab. A usb receiver works with the laser on the bottom of the mouse in determining the pointer's position. As the mouse moves towards the computer (usb receiver), the mouse pointer moves upward on the screen. In the same way, the mouse pointer movers downward as you move the mouse away from the computer. This also works for moving the mouse right and left. This seems like a good application of Physics in improving technology.
