What is Physics?

General Physics is the most fundamental of the sciences , Its goal is to learn how the Universe works at the most fundamental level—and to discover the basic laws by which it operates , Theoretical physics concentrates on developing the theory and mathematics of these laws, while applied physics focuses attention on the application of the principles of physics to practical problems. Experimental physics lies at the intersection of physics and engineering; experimental physicists have the theoretical knowledge of theoretical physicists, and they know how to build and work with scientific equipment.

      Physics is divided into a number of sub-fields, and physicists are trained to have some expertise in all of them. This variety is what makes physics one of the most interesting of the sciences—and it makes people with physics training very versatile in their ability to do work in many different technical fields.

The major fields of physics 2021 are:

Classical mechanics is the study the motion of bodies according to Newton’s laws of motion, and is the subject of this course.

Electricity and magnetism are two closely related phenomena that are together considered a single field of physics.

Quantum mechanics describes the peculiar motion of very small bodies (atomic sizes and smaller).

Optics is the study of light.

• Acoustics is the study of sound.

Thermodynamics and statistical mechanics are closely related fields that study the nature of heat.

• Solid-state physics is the study of solids—most often crystalline metals.

• Plasma physics is the study of plasmas (ionized gases).

• Atomic, nuclear, and particle physics study of the atom, the atomic nucleus, and the particles that make up the atom.

• Relativity includes Albert Einstein’s theories of special and general relativity. Special relativity describes the motion of bodies moving at very high speeds (near the speed of light), while general relativity is Einstein’s theory of gravity.

The fields of cross-disciplinary physics combine physics with other sciences. These include astrophysics (physics of astronomy), geophysics (physics of geology), biophysics (physics of biology), chemical physics (physics of chemistry), and mathematical physics (mathematical theories related to physics .

Besides acquiring a knowledge of physics for its own sake, the study of physics will give you a broad technical background and set of problem-solving skills that you can apply to wide variety of other fields. Some students of physics go on to study more advanced physics, while others find ways to apply their knowledge of physics to such diverse subjects as mathematics, engineering, biology, medicine, and finance. Another benefit of learning physics is that, unlike courses in technology, everything you learn in this course will never be obsolete. Although theories at the cutting edge of physics research may change, the basic physics you’ll learn in these courses will not. You will be able to use what you learn in this course throughout your life.
