Physics

Definition

Physics is the natural science that involves the study of matter, energy, and their interactions. It seeks to understand the fundamental principles that govern the universe, from the smallest particles to the largest galaxies.

Key Concepts

• Mechanics: Study of motion, forces, and energy.
• Thermodynamics: Study of heat, temperature, and energy transfer.
• Electromagnetism: Study of electricity, magnetism, and electromagnetic radiation.
• Optics: Study of light and its interactions with matter.
• Modern Physics: Study of quantum mechanics, relativity, and particle physics.

Important Laws and Principles

• Newton's Laws of Motion: Describes the relationship between the motion of an object and the forces acting on it.
• Law of Conservation of Energy: States that energy cannot be created or destroyed, only transformed from one form to another.
• Law of Universal Gravitation: Describes the force of gravity between two objects.
• First and Second Laws of Thermodynamics: Describe the principles of heat and energy transfer.
• Maxwell's Equations: Describe the behavior of electric and magnetic fields.
• Einstein's Theory of Relativity: Describes the relationship between space, time, and gravity.
