Physics Honors – Lab 04 – Addition of Vectors

Purpose

  • The intent of this activity is to practice adding and manipulating vectors using both graphic and mathematical means.
Procedure
  • Students are given graph paper, rulers and protractors for the assignment.
  • Students are provided with a list of scenarios to attack. For each scenario, students must add the vectors graphically, finding the resultant.
  • NOTE: the graphic method includes using the parallelogram method.
  • Students are then asked to solve the same vector problem using mathematical methods.
  • In both approaches the magnitude and direction of the resultant should be determined.
  • Finally, calculate a percent difference separately for the magnitude and direction of each trial
  • Percent Difference = [(Graphical Result – Math Result)/(Math Result)] x 100%
Notes
  • Each sheet of paper is for one scenario, with the mathematical and graphical solutions being on opposite sides.
  • The assignment will be turned in at the end of the class period on Friday
  • HOMEWORK – Complete the math for all scenarios before Friday’s class period
  • Compilation of results posted [LINK]
