Study Notes
Branches of Physics
- Mechanics: Study of motion, forces, and energy
- Thermodynamics: Study of heat, temperature, and energy transfer
- Electromagnetism: Study of electricity, magnetism, and electromagnetic waves
- Optics: Study of light, vision, and optical instruments
- Quantum Mechanics: Study of behavior of matter and energy at atomic and subatomic level
- Relativity: Study of space and time, including special and general relativity
Key Concepts
- Matter: Anything that has mass and occupies space
- Energy: Ability to do work, comes in various forms (kinetic, potential, thermal)
- Force: Push or pull that causes an object to change its motion
-
Newton's Laws:
- Inertia: Object at rest stays at rest, object in motion stays in motion
- Force and acceleration: F = ma
- Action and reaction: Every action has an equal and opposite reaction
-
Work and Efficiency:
- Work: Force multiplied by distance (W = F × d)
- Efficiency: Ratio of output energy to input energy (η = W_out / W_in)
Important Physicists
- Isaac Newton: Developed laws of motion and universal gravitation
- Albert Einstein: Developed theory of relativity and famous equation E = mc²
- Marie Curie: Discovered radioactive elements and pioneered radioactivity research
- Max Planck: Introduced concept of quantized energy and founded quantum theory
- Niels Bohr: Contributed to understanding of atomic structure and quantum mechanics

Key Concepts
- Matter is anything that has mass and occupies space
- Energy is the ability to do work and comes in various forms, including kinetic, potential, and thermal
- A force is a push or pull that causes an object to change its motion
- Newton's Laws consist of three laws:
- Inertia: an object at rest stays at rest, and an object in motion stays in motion
- Force and acceleration: F = ma
- Action and reaction: every action has an equal and opposite reaction
- Work is the product of force and distance (W = F × d)
- Efficiency is the ratio of output energy to input energy (η = W_out / W_in)
