Physics is the natural science that studies matter, energy, and the fundamental forces of the universe. It seeks to understand how everything in existencefrom subatomic particles to the vast cosmosbehaves, moves, and interacts through space and time. Study.com +3

Check out for a comprehensive deep dive into the discipline.

Physics is broadly divided into two main erasClassical Physics and Modern Physicswhich are then broken down into several specialized fields.

1. Classical Physics (Macro-scale)

Deals with macroscopic objects and phenomena where speeds are significantly slower than the speed of light. Study.com +4

• Mechanics: The study of motion, forces, gravity, and the behavior of physical bodies at rest or in motion (e.g., Newton’s laws of motion).
• Thermodynamics: The study of heat, temperature, and the relationship between heat, work, and energy.
• Electromagnetism: The study of electric and magnetic fields, charges, and how they interact to create forces and power technologies.
• Optics: The study of light, its properties, and its interactions with matter, including reflection, refraction, and lenses.
• Acoustics: The study of sound, vibration, and wave mechanics.
