Introduction: What Is Physics
What is physics is one of the most fundamental questions in science. Physics is the branch of science that seeks to understand how the universe works—from the smallest particles to the largest galaxies.
In the first 10% of this article, it is essential to clarify that what is physics is not limited to formulas or experiments in laboratories. Physics explains motion, energy, light, sound, gravity, electricity, and the laws that govern the natural world.
Definition and Meaning of Physics
Physics is defined as the scientific study of matter, energy, space, time, and their interactions. The word physics comes from the Greek word physika, meaning “nature.”
In simple terms:
Physics explains why things move, how forces act, and how energy changes form.
Understanding what is physics helps us interpret everyday phenomena, from falling objects to wireless communication.
