Understanding Base Quantities & Derived Quantities

 

• Physical Quantity is a quantity that can be 

  measured.

• Base Quantity is a physical quantity that 

  cannot be defined in terms of other physical 

  quantities.

• Derived Quantity is a combination of base 

  quantity by multiplication, division or both 

  these operation.

 

 Example of derived quantity:

Other examples: force, acceleration, electric charge, momentum & etc

What is Physics?

Physics is a natural science that involves the study of matter and its motion through spacetime, as well as all related concepts, including energy and force, heat, sound, light, magnetism, electricity & the composition of atoms. More broadly, it is the general analysis of nature, conducted in order to understand how the universe behaves.

Physics can be divided into 2:

1. Physical Science
2. Biological Science

Physical science concerned with the properties & behaviour of non-living matter.

Biological science deal with living organisms.
