Introduction to Physics

Physics

• Physics is the natural science studying matter, its motion and behavior through space and time, and related energy and force concepts.
• Key areas include classical mechanics, electromagnetism, thermodynamics, optics, and modern physics (relativity and quantum mechanics).
• Classical mechanics describes object motion under forces, including Newton's laws.
• Electromagnetism studies electric and magnetic field interactions, including light.
• Thermodynamics deals with heat, temperature, and energy transfer.
• Optics studies light behavior, including reflection, refraction, and diffraction.
• Modern physics explores atomic and subatomic phenomena, relativity, and quantum mechanics.
• Relativity describes the relationship between space and time and high-speed object behavior.
• Quantum mechanics describes matter and energy behavior at atomic and subatomic levels.
• Fundamental forces include gravity, electromagnetism, strong nuclear, and weak nuclear forces.
• Units like meters, kilograms, seconds, and amperes are crucial.
• Mathematical tools like calculus, differential equations, and linear algebra are essential.
• Physics principles are applied in engineering, astronomy, and material science.
• Key figures include Newton, Einstein, and Maxwell.

Chemistry

• Chemistry studies matter's composition, structure, properties, and reactions.
• It studies elements, compounds, and their interactions.
• Key areas include organic chemistry (carbon-containing compounds), inorganic chemistry (elements without carbon), physical chemistry (property-reaction relationships), and analytical chemistry (matter composition).
• Atoms are the fundamental matter building blocks, composed of protons, neutrons, and electrons.
• Elements are pure substances of one atom type.
• Compounds are substances formed by chemically combining elements.
• Chemical reactions involve breaking and forming chemical bonds, transforming substances.
• Chemical bonds hold atoms in molecules and compounds.
• States of matter include solid, liquid, and gas, each with unique properties.
• Solutions are homogeneous mixtures of two or more substances.
• Periodic tables organize elements based on atomic structure and properties.
• Chemical equations represent reactions, showing reactants and products.
• Valence electrons are involved in chemical bonding.
• Acids and bases are essential chemical classifications based on pH.
• Chemical formulas represent compound composition.

Biology

• Biology is the scientific study of life and living organisms.
• Key areas in biology range from molecular biology to ecology to evolutionary biology.
• Cells are the fundamental units of life.
• Genetics studies genes, heredity, and organism variation.
• Ecology studies interactions between organisms and their environment.
• Evolution is the process by which populations change over time.
• Organisms are classified into taxonomic groups based on evolutionary relationships and shared characteristics.
• Molecular biology studies biological molecules like DNA, RNA, and proteins.
• Organisms have tissues, organs, and organ systems.
• Biological processes include photosynthesis, respiration, and reproduction.
• Biological systems adapt to environmental changes, often exhibiting heritable traits.
• Biodiversity is the variety of life on Earth at all levels (genes to ecosystems).
• Microbiology studies microorganisms (bacteria, viruses, and fungi) vital to biological processes.
• Physiology studies living organism and system functions.
• Organisms respond to stimuli from their surroundings, like plants growing towards sunlight.
• Basic biological concepts include DNA, RNA, and proteins as central to life processes.
