Core Concepts:
* Motion & Forces: Understanding how objects move and the forces that act upon them (gravity, friction, etc.).
* Energy: The ability to do work, its different forms (kinetic, potential, thermal), and how it's transferred.
* Matter: The stuff the universe is made of, its properties, and how it interacts at the atomic and subatomic levels.
* Waves: Disturbances that transfer energy through a medium (sound, light, water waves).
* Thermodynamics: The study of heat and its relationship to energy and work.
* Electricity & Magnetism: The forces and phenomena related to electric charges and magnetic fields.
* Quantum Mechanics: The study of the very small, including particles, atoms, and the weirdness of the quantum world.
* Relativity: Einstein's theories of special and general relativity, dealing with space, time, gravity, and the universe at large.
* Cosmology: The study of the origin, evolution, and structure of the universe.
Key Tools & Methods:
* Mathematics: Physics relies heavily on math for describing phenomena, developing theories, and making predictions.
* Experimentation: Designing and conducting experiments to test hypotheses and gather data.
