• Procedure
• Using a ruler, construct a vector diagram based
  on the dimensions provided. You will then make a
  rectangle based on your x and y values. Accuracy
  in measuring is important!
• Draw a diagonal within your rectangle to
  represent the resultant of the x and y vector
  components.
• Use a ruler to measure the length of the diagonal
  to the tenth of a cm. Next, calculate the
  resultant using the Pythagorean theorem. Record
  in your table.

Experimental resultant (exp) use a ruler to
measure the diagonal line in cm (I got 30 cm)

Analysis

1. What appears to be the relationship between the
   horizontal component and the resultant for each
   diagram?
2. What appears to be the relationship between the
   vertical component and the resultant for each
   diagram?
3. So, in general, what pattern do you notice
   related to the resultant for each of the diagrams?
