Branches of Physics

1. Mechanics

   • Definition: Deals with motion and the forces acting on objects.
   • Example: Studying how a car moves or how planets orbit the sun.

2. Thermodynamics

   • Definition: Focuses on heat, temperature, and their relationship to energy and work.
   • Example: Working of a refrigerator or steam engines.

3. Optics

   • Definition: Study of light and its behavior.
   • Example: Functioning of lenses in glasses or cameras.

4. Electromagnetism

   • Definition: Concerns electricity, magnetism, and their interactions.
   • Example: Designing electric circuits or understanding magnetic fields.

5. Acoustics

   • Definition: The study of sound and sound waves.
   • Example: Designing concert halls for better sound quality.

6. Quantum Mechanics

   • Definition: Explores the behavior of particles at the atomic and subatomic levels.
   • Example: Behavior of electrons in atoms.

7. Nuclear Physics

   • Definition: Studies atomic nuclei, their structure, and reactions.
   • Example: Nuclear energy production.

8. Astrophysics

   • Definition: Applies physics to understand celestial bodies and the universe.
   • Example: Studying black holes or the Big Bang theory.

9. Fluid Mechanics

   • Definition: Examines the behavior of liquids and gases in motion.
   • Example: Designing ships or predicting weather patterns.

10. Relativity

• Definition: Focuses on the relationship between space and time as proposed by Einstein.
• Example: GPS systems functioning accurately due to time dilation effects.
