Question

List the seven fundamental units of physical quantity. Give their units and application.​

Answer 1

The seven fundamental physical quantities in physics are length, mass, time, electric current, temperature, amount of substance, and luminous intensity. These quantities are measured in units such as meters, kilograms, and seconds. Other physical quantities can be expressed as combinations of these fundamental units.

Step-by-step explanation:

In physics, there are seven fundamental physical quantities that are measured in base or physical fundamental units: length, mass, time, electric current, temperature, amount of substance, and luminous intensity.

The units for these fundamental quantities are:

1. 
   
3. 
   
5. 
   
7. 
   
9. 
   
11. 
    
13. 
    

These fundamental units are used to express other quantities. For example, force can be expressed as mass times acceleration (kg·m/s²) and energy can be expressed as mass times distance squared divided by time squared (kg·m²/s²).
