Vector diagram

• What can you calculate using vector diagrams?

  The resultant of two forces at an angle
• What is the term for a single force that replaces multiple forces?

  Resultant force
• What is the first step in calculating the resultant force at an angle?

  Make a scale drawing of the forces
• If 1 cm equals 1 Newton, how long should the arrow be for a 10 Newton force?

  10 cm
• What shape do you create to find the resultant force?

  A parallelogram
• How do you convert the length of the resultant vector to Newtons?

  Multiply by the scale factor
• If the resultant vector is 17.5 cm, what is the resultant force in Newtons?

  17.5 Newtons
• What are the steps to calculate the resultant force using vector diagrams?

  1. Draw a scale diagram of the forces.
  2. Use a ruler to draw the force vectors.
  3. Measure the angle between the forces.
  4. Complete the parallelogram.
  5. Measure the resultant vector's length.
  6. Convert the length to Newtons using the scale.
• What are the key components of a vector diagram for resultant forces?

  • Scale representation of forces
  • Accurate angle measurement
  • Parallelogram construction
  • Resultant vector length measurement
