Overview of Physics

Physics investigates the interactions of matter, force, and energy.
Divided into classical physics (before 1900) and modern physics (after 1900).

Classical Physics

Defined as all discoveries and principles established prior to 1900.
Major branches include:
- Mechanics: Focuses on motion, force, work, energy, and fluids.
- Heat and Thermodynamics: Examines heat's effects on a system, heat transfer methods, and conversion of heat energy to mechanical energy.
- Optics: Studies the properties and behavior of light.
- Electricity and Magnetism: Explores phenomena related to electrical charges and their interactions with magnetism.
- Wave Motion and Sound: Investigates properties, transmission, and perception of different wave types.
Engages with macroscopic objects and phenomena at speeds significantly less than the speed of light (approximately 3x10^8 m/s in vacuum).

Modern Physics

Commenced with Max Planck's discovery of blackbody radiation in 1900.
Major areas include:
- Nuclear Physics: Studies atomic nucleus properties and reactions.
- General Relativity: Describes how matter influences space-time curvature, affecting the trajectory of matter and light.
- Special Relativity: Looks at effects on objects moving at speeds close to light speed.
- Particle Physics: Investigates elementary particles, the fundamental building blocks of matter.
- Quantum Mechanics: Analyzes the nature and behaviors of matter and energy at atomic and subatomic scales.

This quiz covers the fundamentals of physics, including its major branches like classical and modern physics. It explores the interactions of matter, force, and energy, as well as key concepts in mechanics, thermodynamics, optics, electricity, magnetism, and wave motion. Test your knowledge on the definitions and principles established in the field of physics.
