Today in class we had a number of objectives to complete. They were to first collect equations shirt money, check our homework, read and complete our Daily Question which was graded, review our homework (Vector Addition: Physics 1), and to do more vector addition problems (Vectors, Distances, and Displacements: Physics 1). Our Daily Question was: Using the scale of 3 centimeters = 50 Newton’s and the graph paper draw the vector representation for a force of 175 Newton’s in the 205 degree direction. In order to solve the problem given I first set up an equation so the X value could be isolated. The 3 centimeter value was over the 50 Newton value equaling the X value over the 175 Newton value. Then I cross multiplied and ended up with 50x = 525. Then I divided both sides by 50 in order to obtain the X value of 10.5 centimeters.



One homework problem on our Vector Addition: Physics 1 assignment was this: Mr. Physics drove from his home in his Honda Accord; 45 km in the 25 degree direction then turned in the 105 degree direction and drove another 70km. What was his final displacement from home? I started by choosing my scale which was 10 kilometers for every one centimeter. Then I measured out a 25 degree angle and drew a line in that direction that was 4.5 centimeters long. Then I measured out a 105 degree angle from the tip of the previous vector’s arrow head that was 7 centimeters in length. After both vectors were complete I drew the Resultant Vector from my last arrow head to the start of the first vector. Then I measured the angle and length of the Resultant Vector and came up with 89.6 km @ 75.3 degrees.
