Written & reviewed by James Millett — Biology (Imperial College London), PGCE Science (University of Cambridge).

Model answer (4 marks)

A scalar quantity has magnitude only.
A vector quantity has magnitude and direction.
Example of a scalar: mass.
Example of a vector: force.

Examiner tips

  • Use the word "has" to show the property. Give one example for each type. Keep the answer short and to the point.

Common mistakes

  • Mixing up scalar and vector examples. Using a vector as a scalar example (e.g. speed as a vector).

Mark scheme (4 marks)

  1. A scalar quantity has magnitude only
  2. A vector quantity has both magnitude and direction
  3. Correct example of a scalar quantity (e.g. distance, speed, time, mass, energy, temperature)
  4. Correct example of a vector quantity (e.g. displacement, velocity, acceleration, force, weight, momentum)
