CLASSICAL PHYSICS

Options

A. Mechanics
B. light
C. heat
D. elementary particles

Answer

To answer the question regarding what is included in classical physics, we can break down the information provided in the video transcript into a clear step-by-step solution.

### Step-by-Step Solution:

1. **Definition of Classical Physics**:
Classical physics is a branch of physics that deals with the laws of motion, gravitation, electromagnetism, thermodynamics, and wave phenomena. It primarily focuses on macroscopic phenomena and does not consider quantum effects.

2. **Components of Classical Physics**:
Classical physics includes various subjects such as:
- Mechanics: The study of motion and forces.
- Electromagnetism: The study of electric and magnetic fields and their interactions with matter.
- Thermodynamics: The study of heat and temperature and their relation to energy and work.
- Wave phenomena: The study of waves, including sound and light.

3. **Exclusions from Classical Physics**:
Classical physics does not encompass:
- Quantum Mechanics: The study of physical phenomena at the scale of atoms and subatomic particles.
- Relativity: The theory proposed by Einstein that describes the physics of objects moving at high speeds and the effects of gravity on the fabric of space-time.
- Field Theory: The study of how fields (like electromagnetic fields) interact with particles.

4. **Specific Focus on Light and Heat**:
Light and heat are both phenomena that can be described by classical physics through the lens of electromagnetism. They are not excluded from classical physics.

5. **Conclusion**:
Based on the information provided, the primary subject that is not included in classical physics is mechanics, as it is often associated with more advanced theories in modern physics.

### Final Answer:
Mechanics is not included in classical physics.
