Answer 2

Answer:

The physical quantities have been classified as Vectors and Scalars:

(i) Displacements - Vector

(ii) Distance traveled - Scalar

(iii) Velocity - Vector

(iv) Speed - Scalar

(v) Force-Vector

(vi) Work done - Scalar

(vii) Energy - Scalar

Explanation:

​Vectors have both magnitude and direction, whereas scalars only have magnitude. In the given options, displacements, velocity, force, work done, and energy all have both magnitude and direction, so they are vectors.

Distance traveled and speed, on the other hand, only have magnitude and do not have a direction associated with them, so they are scalars.

(i) Displacements - Vector

(ii) Distance traveled - Scalar

(iii) Velocity - Vector

(iv) Speed - Scalar

(v) Force-Vector

(vi) Work done - Scalar

(vii) Energy - Scalar
