Question

20 examples of scalar and vector quantities.

Answer 1

As we know that the scalar quantity is defined as the physical quantity that has only magnitude. On the other hand, a vector quantity is defined as the physical quantity that has both magnitudes as well as direction.

And the vector and scalar difference is Vectors have magnitude and direction but scalars have only magnitude.

Following are the Examples of scalar quantity:

1. Distance
2. Speed
3. Mass
4. Temperature
5. Energy
6. Work
7. Volume
8. Area
9. Pressure
10. Power
11. Time
12. Current
13. Entropy
14. Cost
15. Frequency
16. Size
17. Length
18. Calories
19. Density
20. Refractive index

Answer 2

The physical quantity having simply magnitude and no direction is known as a scalar quantity. Without guidance, some physical quantities can be defined just by their numerical value. These physical quantities are added using basic algebraic procedures, and just their magnitudes are added here.

A physical quantity with both directions and magnitude is referred to as a vector quantity.

The unit vector is a vector having a magnitude of one and a direction of one. It is represented by a lowercase alphabet with a "hat" circumflex. "û" is the correct spelling.
