Revision: steps to draw a vector diagram


  1. Choose a scale.
  2. Draw a small point as the body.
    (you can do 2 before 1 as well)
  3. Draw the forces acting on the body according to the scale chosen. (label the forces properly, remember the arrows too)
  4. Draw the dotted lines to form the parallelogram.
  5. Form the resultant force by connecting the small point (from step 2) with the opposite vertex (official name for the "edge" of any shape). (remember the double arrow)
  6. Measure the resultant force and the angle it makes.

Template for concluding statement:

The resultant force is _______ N and it makes an angle of ______ with the ____ force.



Try not to say "with the horizontal force" because in examinations, the orientation may not be the same for different questions.


(please note that this will come out for your common test)
