• Chemical reactions and compounds

• The study of stars and planets

• Biological processes and organisms

• Matter, energy, motion, and force

Physics is often referred to as "the pioneer science" because:

• It forms the basis for other natural sciences and provides fundamental laws that govern them.

• It deals with the development of technology and engineering.

• It focuses primarily on the study of ancient civilizations.

• It was the first science ever discovered.

Why is physics known as "the fundamental science"?

• It focuses on the practical applications of chemistry.

• It provides the basic principles and laws that underpin all other scientific disciplines.

• It primarily deals with the study of biological systems.

• It is concerned with the historical aspects of scientific development.

Measurement in physics refers to the process of quantifying physical quantities or properties of objects and phenomena.
