Study Notes
Physics
- Physics is the natural science involving the study of matter, its motion through space and time, and related concepts like energy and force.
Classical Mechanics
- Classical mechanics describes the motion of macroscopic objects.
- It uses concepts of space, time, mass, force, momentum, and energy to predict and explain object and system motions.
- Key figures include Isaac Newton, who formulated the laws of motion and universal gravitation.
- Newton's laws connect object motion to the forces acting upon it.
Quantum Mechanics
- Quantum mechanics describes the properties of nature at the atomic and subatomic levels.
- Quantum mechanics significantly differs from classical mechanics at these scales.
- Quantum states are quantized, meaning they have specific discrete values, unlike the continuous nature of classical properties.
- Key concepts are wave-particle duality, superposition, and entanglement.
- Quantum mechanics has advanced technologies like lasers, transistors, and medical imaging.
Thermodynamics
- Thermodynamics describes heat, work, and energy relationships in a system.
- It includes thermodynamic equilibrium, entropy, and the laws of thermodynamics, governing energy transfer direction and limitations.
- The zeroth, first, second, and third laws define energy transfer rules and their system effects.
- Applications range from engine power generation to chemical reaction behavior.
Electromagnetism
- Electromagnetism studies the relationship between electric and magnetic fields.
- Electric and magnetic fields are interconnected; changing magnetic fields create electric fields, and vice versa.
- Fundamental to technologies like electric motors, generators, and electromagnetic waves.
- Maxwell's equations summarize electromagnetism's key relationships.
Relativity
- Relativity describes spacetime, gravity, and object behavior at high speeds or strong gravitational fields.
- Special relativity deals with constant velocity object behavior.
- General relativity describes gravity as spacetime curvature caused by mass and energy.
- Einstein's theories have implications for cosmology, astrophysics, and black hole behavior.
Optics
- Optics studies light's behavior and properties, focusing on reflection, refraction, and interference.
- Applications include telescopes, microscopes, lenses, and optical communication fibers.
Atomic and Nuclear Physics
- Atomic physics examines atomic structure and behavior.
- Nuclear physics studies atomic nuclei's structure, behavior, and interactions, closely related to atomic physics.
- Explains phenomena like radioactivity and nuclear reactions.
- Understand atomic and nuclear properties are important for applications like energy generation and medical imaging.
Particle Physics
- Particle physics studies fundamental matter constituents and the acting forces.
- It explores elementary particles and their interactions.
- The Standard Model describes fundamental particles and forces.
- Particle physics research expands our understanding of the universe and governing laws.
Other Branches of Physics
- Condensed Matter Physics: Studies collective atom/molecule behavior in solids and liquids.
- Biophysics: Applies physical principles to biological systems' molecular/cellular structure and function.
- Astrophysics: Applies physical principles to celestial objects (stars, planets, galaxies, universe).
- Geophysics: Uses physical principles to understand Earth's structure, processes, and phenomena (earthquakes, plate tectonics).
