Lab 4: Vectors Part C: Precise Vector Diagrams Graphical methods require a precisely drawn diagram with carefully measured lengths and angles. When graph paper is used, each grid line represents a fixed amount of some physical quantity. For instance, when drawing a velocity vector using graph paper, each grid line may represent 10 m/s. This is called a scale factor. You draw each vector using the tip to tail method 1. Components of vectors. The vector in this problem is a displacement vector that starts at the origin, has a magnitude of 12 km and has a direction of 35 degrees (measured counter clockwise from the +x axis). a. Using the gridlines below (0.5 cm spacing), draw the vector. Use a scale factor of 1 km per grid line. Use a protractor and ruler to make sure your vector has the correct magnitude and direction. b. Draw a dotted line from the tip of the vector to the x axis. Using a ruler, measure the the x component in.cm, and use the scale factor to convert to km. c. Draw a dotted Jine from the tip of the vector to the y axis. Using a ruler, measure the the y component, and use the scale factor to convert to.km.
