Question

Mass is a ______ quantity and weight is a ______ quantity.

• A. scalar
• B. vector

Answer 1

1. Physical quantities are classified into scalar and vector quantities.
2. Scalar quantities have only magnitude.
3. Vector quantities have both magnitude and direction.
4. Mass is a physical quantity that has only magnitude, so it is scalar.
5. Weight is the force experienced by the body due to its mass, Hence it has both magnitude and direction.

Hence mass is a scalar quantity and weight is a vector quantity.
