Question

3. Explain giving examples. (a) Scalar quantity (b) Vector quantity​

Answer 1

Answer:

Quantities that only have magnitude, are called scalars. . Some examples of scalars are mass, density, time, temperature, volume, energy, speed, etc. These quantities can be described using a number only. Examples of vectors are weight, displacement, force, velocity, etc.

Answer 2

scalar Quantity: Any physical quantity , which can

be completely magnitude alone is scalar Quantity

Eg: Time, distance

Vector Quantity: Any physical quantity, which requires direction in addition to it's magnitude is known as vector Quantity

Ex: velocity, displacement
