Welcome to the Physics Learning Journey!
Physics is all about the things around us – Light, Sound, Gravity, and so on.
Understanding the Physics concepts lays foundation to your learning.
I will be explaining each topic in an easy way to understand and retain.
Definition of Physics
Physics is a branch of science that studies matter, its motion, and behavior through space and time. It also involves related concepts such as energy and force.
Physics is one of the most fundamental scientific disciplines, aiming to understand how the universe behaves at every scale, from the smallest subatomic particles to the largest galaxies.
Major Topics in Physics
Physics is a vast and diverse field of study, encompassing many different areas. I have given some of the major topics classified in physics below.
These classifications are not exhaustive, but they provide a broad overview of the different areas within the field of physics. Each topic has its own set of subtopics and specialized areas of study.
Classical Mechanics: The study of the motion of objects and the forces that cause this motion. It includes concepts such as Newton’s laws, kinematics, and dynamics.
Thermodynamics: The study of heat, work, energy, and the laws governing their interactions. Key concepts include temperature, entropy, and the laws of thermodynamics.
Electromagnetism: The study of electric and magnetic fields, their interactions, and their effects on matter. This includes topics such as electric circuits, electromagnetic waves, and Maxwell’s equations.
Optics: The study of light and its interactions with matter. It covers topics such as reflection, refraction, diffraction, and polarization.
Quantum Mechanics: The study of the behavior of particles at the atomic and subatomic levels. It includes principles such as wave-particle duality, the uncertainty principle, and quantum states.
Relativity: The study of the effects of gravity and motion on space and time. It includes Einstein’s theories of special relativity and general relativity.
Nuclear Physics: The study of the components and behavior of atomic nuclei. It includes topics such as radioactivity, nuclear reactions, and nuclear energy.
Particle Physics: The study of fundamental particles and the forces that govern their interactions. It covers topics such as the Standard Model, particle accelerators, and high-energy collisions.
Condensed Matter Physics: The study of the properties of matter in solid and liquid states. It includes topics such as crystallography, superconductivity, and magnetism.
Astrophysics and Cosmology: The study of the universe and its contents, including stars, galaxies, and the overall structure of the cosmos. It covers topics such as the Big Bang theory, black holes, and the expansion of the universe.
