TPJ Meghan Amberik Pd. 4

Today's Objectives: T-shirts, Graded Daily Question, Review Answers, Vector Addition, and HW Homework: Page 16 due Tuesday

When first walking into class, there was a packet, graph paper, and a half sheet of paper on the front desk. After picking up each paper we had to start working on our graded daily question on the half sheet.

DQ: Draw a vector that is: 1. 7.35 cm @ 82.0 degrees 2. 45.1 mm @ 317.0 degrees Answers:

After Mr. Manning collected our half sheets, he reminded the class that the physics t-shirt money is due tomorrow. The shirts are $6.90 and checks must be made out to MTHS PHYSICS. We then went over the packet (pages 12 and 13) that we did in class on Friday. After going over each problem, we started to learn about vector addition. Mr. Manning explained the directions on page 14. When doing these problems you first have to choose a scale. You then have to calculate the length of each vector. Next you draw the first vector, then you start the second vector at the head of the first and you start the third on the head of the second. After drawing the three vectors, you draw the sum of the vectors and determine the magnitude and direction of the forces. We then did the first problems on page 15 together as a class. The rest of the problems were assigned to work on in class and we had to finish up both pages for homework if we didn't get it finished.
