12-12

On Friday in Physics class, we picked up a piece of graph paper and pages 19 and 20. We learned something new called components. The worksheet 19 that you picked up explains how to do that. It's basically the same as what we've been doing, but it's even easier. You just draw the line with the given degrees and length (which you will still have to solve to convert to centimeters), and then follow the direction it says to go. Then draw the component along the North/South axis and the East/West (one of each). The picture attached to this TPJ, that I drew is an example of how to do one. Then all you have to do it measure those new lines and convert it back into your measurements (for example, convert centimeters back into meters/second according to your original scale). We were given time in class to work on pages 19 and 20. It does not take too much time because it is easier than the subtraction and addition vectors which we have been doing previously doing. That worksheet was homework that is due on Monday if you did not complete it during class. The answers to these problems that Mr. Manning provided for us are as follows: 1. a) 129 m/s b) 153 m/s 2. a) 96.4 N b) 115 N 3. a) 2.50 N b) 4.33 N 4. 11.5 yards.

There is a quiz on Monday on vector addition, subtraction vectors, and the thing we learned on Friday (Components). To study for this quiz, just review over all the notes on the 2 vectors (addition and subtraction) and the components worksheet. Picture (example): [|TPJdec12.bmp]
