# Classify the following as scalar and vector quantities.

(i) time period (ii) distance (iii) force

(iv) velocity (v) work done

Answer :

Scalars are defined as quantities that have magnitude only.

Vectors are defined as a quantity that has magnitude as well as direction.

(i) **time period:** It is a __scalar__ quantity as it has magnitude only and no direction.

(ii) **distance:** It is a __scalar__ quantity as it has magnitude only and no direction.

(iii) **force:** It is a __vector__ quantity as it has magnitude as well as direction.

(iv) **velocity:** It is a __vector__ quantity as it has magnitude as well as direction.

(v) **work done:** It is a __scalar__ quantity as it has magnitude as well as direction.
