Physics
* The study of the fundamental constituents of the universe and their interactions.
Branches of Physics:
1. Classical Physics:
* Mechanics:
* Kinematics: Motion of objects without considering the forces causing them.
* Dynamics: Motion of objects under the influence of forces.
* Newtonian Mechanics: Laws of motion, gravity, and inertia.
* Lagrangian Mechanics: Describes motion using energy and generalized coordinates.
* Hamiltonian Mechanics: Describes motion using energy and momentum.
* Thermodynamics:
* Heat: Transfer of energy due to temperature differences.
* Temperature: Measure of the average kinetic energy of particles.
* Entropy: Measure of disorder or randomness in a system.
* Optics:
* Geometric Optics: Study of light rays and their interaction with lenses and mirrors.
* Wave Optics: Study of the wave nature of light and phenomena like interference and diffraction.
* Physical Optics: Study of the electromagnetic nature of light and its interactions with matter.
* Electromagnetism:
* Electricity: Study of electric charges and their interactions.
* Magnetism: Study of magnetic fields and their interactions with charged particles.
