Question
Which of the following is not a vector quantity:
  1. Speed
  2. Density
  3. Force
  4. Velocity
✓

Answer

  1. Density
Solution:
Density is a scalar quantity as it has only magnitude but no direction. Speed, force, velocity has both magnitude and direction.
$\therefore$ They all are vectors.
