Vector Addition Activity Equipment: Name ______________________________ scratch paper rulers protractors Introduction: In this lab you will perform vector force addition by Algebraic and Graphical and methods. Table 1. Vectors Algebraic Graphical Use (cm) Resultant, R (grams) Resultant, R (grams) (magnitude and direction) (magnitude and direction) a Pencil F1 10cm @ 30 F2 10cm @ 60 F1 10cm @ 0 F2 10cm @ 150 F1 10cm @ 0 F2 15cm @ 90 Vector addition 1 Vector addition 2 Vector addition 3 Part I. Algebraic Vector Addition F x F1 cos 1 F2 cos 2 and F y F1 sin 1 F2 sin 2 tan 1 Fy F x 1. Use the equations above to solve for the magnitude Fnet and direction of the Fnet F F 2 x 2 y and resultant of adding F1 10cm @ 30 and F2 10cm @ 60 . Enter Fnet and in Table 1.

Use the equations above to solve for the magnitude Fnet and direction of the resultant of adding F1 10cm @ 0 and F2 15cm @ 90 . Enter Fnet and in Table 1. Page 2 of 5 CYP Labs Part II. Graphical Vector Addition You will now add the same vectors by using the graphical tail-to-head method. Use a ruler and protractor. Plan ahead so you don’t run out of room on your paper. Measure the magnitude of the resultant vector in cm on your paper. Also measure the Resultant angle. Record both in Table 1 for each one. 1. Use Graphical Vector Addition to find the magnitude Fnet and direction of the resultant of adding F1 10cm @ 30 and F2 10cm @ 60 . Enter Fnet and in Table 1. Show a graph from your group to your instructor before you proceed to the next step. Page 3 of 5 CYP Labs 2.
