1.1 What is physics?

CLASS-XI PHYSICS + NEET Chapter-1: Physical World 1.1 What is physics?

What is Physics?

Physics is the study of matter, basic principles, and laws of nature along with their manifestations.

Definition of the Physical World?

The physical world is the only world that we see around us that is real. The study of physics is mainly involved in the explanations of the diverse phenomena of its concepts. In Physics, we attempt to explain diverse physical phenomena in terms of a few concepts and laws. The effort is to see the physical world as the manifestation of some universal laws in different domains and conditions. For example, the same law of gravitation (given by Newton) describes the fall of an apple to the ground, the motion of the moon around the earth, and the motion of planets around the sun. Similarly, the basic laws of electromagnetism (Maxwell’s equations) govern all electric and magnetic phenomena.
