Introduction to Physics

Study Notes

Classical Physics
- Encompasses traditional forces and principles established before the 20th century.
Modern Physics
- Focuses on theories and concepts that have developed since the early 20th century.

Acoustics
- Studies sound, including its transmission, production, and effects.
- Involves mechanical waves like vibration, sound, ultrasound, and infrasound.
Mechanics
- Examines the motion of objects under various forces and conditions.
- Divided into:
  - Classical Mechanics: Laws of motion and forces on macroscopic objects.
  - Quantum Mechanics: Behavior of subatomic particles.
Optics
- Investigates the behavior, propagation, and properties of light.
Thermodynamics
- Studies heat and its conversion into work and energy.
- Involves heat transfer mechanisms: convection, conduction, and radiation.
Electromagnetism
- Analyzes the interaction of electric and magnetic fields.
- Comprised of two key aspects: electricity and magnetism.

Classical Physics
- Relates to traditional forces identified before the twentieth century.
Modern Physics
- Encompasses concepts developed after the twentieth century.
