Physics
Physics is the branch of science that studies matter, energy, and the fundamental forces of nature. It explores concepts like motion, force, gravity, electricity, magnetism, heat, light, and atomic structure. Physics helps explain how the universe behaves and underpins modern technologies like electronics, aviation, and nuclear energy.
Electromagnetism
The study of electric and magnetic fields and how they interact with each other and with matter.
Gravitation
The study of the force of attraction between masses, described by Newton’s Law of Universal Gravitation and Einstein’s General Relativity.
Kinematics
The study of motion without considering the forces that cause it; includes velocity, acceleration, and displacement.
Laws of Thermodynamics
Fundamental principles describing how energy moves and changes form, especially heat and work.
Modern Physics
Covers concepts developed in the 20th century, including quantum mechanics, relativity, and atomic structure.
Newton's Laws of Motion
Three fundamental laws that describe the relationship between the motion of an object and the forces acting on it.
Nuclear Physics
The study of the components and behavior of atomic nuclei, including radioactivity and nuclear reactions.
Optics
The branch of physics dealing with the behavior of light, including reflection, refraction, and lenses.
Waves and Sound
The study of wave behavior (such as reflection, refraction, and interference) and how sound propagates through different media.
Work, Energy, and Power
Concepts that describe how forces do work, how energy is transferred, and the rate at which work is done.
