Which of the following quantities is NOT a vector quantity?

Show answer & explanation

Correct answer: A

Explanation

The correct answer is option 1 i.e. Work.

Vector and Scalar quantities:
  • The quantity is either a vector or a scalar.
  • Scalars are quantities that are fully described by a magnitude (or numerical value) alone.
  • Vectors are quantities that are fully described by both a magnitude and a direction.

Work:
  • Work is defined as a dot-product (or scalar product) of force and displacement, both of which are vectors.
  • A scalar product of two vectors gives a scalar result.
