Physics

• Fundamental quantities in the SI system include length, mass, time, electric current, temperature, amount of substance, and luminous intensity; derived quantities are formed from these.
• Measurement errors are classified into systematic and random errors, impacting precision and accuracy.
• Distance refers to the total path traveled, while displacement is the shortest path from initial to final position.
• Speed is a scalar quantity; velocity includes direction, and acceleration measures the rate of change of velocity.
• Equations of motion for uniformly accelerated motion include v = u + at and s = ut + 0.5at².
• Newton's First Law establishes the concept of inertia; the Second Law quantifies force (F = ma), and the Third Law states action and reaction forces are equal and opposite.
• Work is defined as force applied over a distance; energy is the capacity to do work. Power is the rate of doing work.
• Kinetic energy (KE = 0.5mv²) and potential energy (PE = mgh) are the two primary energy forms; energy conservation implies total energy remains constant in closed systems.
• The center of mass is the average position of all mass in a system, affecting motion; torque is the rotational equivalent of linear force.
• Angular momentum is conserved in an isolated system, similar to linear momentum.

Chemistry

• The mole is a fundamental unit for measuring the amount of substance, with Avogadro's number (6.022 x 10²³) representing the number of particles in one mole.
• Stoichiometry involves quantitative relationships in chemical reactions, enabling calculations like yield and reactant/product quantities.
• Dalton's atomic theory posits that matter is composed of indivisible atoms; electrons, protons, and neutrons form atomic structure.
• The quantum mechanical model describes electrons in terms of densities and probabilities rather than fixed orbits.
• The periodic table organizes elements based on atomic number; trends include increasing atomic size down a group and higher ionization energy across a period.
• Atoms can be classified as metals, non-metals, or metalloids based on their properties.
• Chemical bonding includes ionic bonds (transfer of electrons) and covalent bonds (sharing of electrons), influencing molecular properties and structures.
• VSEPR theory predicts molecular shapes based on repulsion between electron pairs; hybridization explains bonding in complex molecules.
• Properties of solids include rigidity and a definite shape; liquids have fixed volume but adapt shape, while gases have neither fixed volume nor shape.
• Boyle's Law (P1V1 = P2V2) relates pressure and volume; Charles's Law (V1/T1 = V2/T2) connects volume and temperature; Avogadro's Law states equal volumes of gases contain the same number of particles.

Biology

• Living organisms are classified into five kingdoms: Monera, Protista, Fungi, Plantae, and Animalia based on characteristics such as cell structure and nutrition.
• Taxonomy is the science of classifying organisms; binomial nomenclature provides a two-part scientific naming system (genus and species).
• Cell types: prokaryotic cells lack a nucleus, while eukaryotic cells have membrane-bound organelles.
• Plant and animal tissues are categorized into types: epithelial, connective, muscle, and nervous tissue in animals; and parenchyma, sclerenchyma, and xylem/phloem in plants.
• Organelles like mitochondria (energy production), endoplasmic reticulum (protein/lipid synthesis), and nucleus (genetic material) are critical for cell function.
• Cell division occurs through mitosis (somatic) and meiosis (gamete formation), enabling growth and reproduction respectively.
• Photosynthesis converts sunlight into chemical energy, producing glucose and oxygen; respiration breaks down glucose to release energy.
• Xylem transports water and nutrients, while phloem transports sugars and metabolites.
• The human body consists of systems (digestive, circulatory, respiratory) that work together for overall physiology; hormones regulate various physiological activities.

Mathematics

• Sets are collections of distinct objects; operations include union, intersection, and difference; types of sets include finite, infinite, and empty sets.
• Functions express relationships between sets, with domain (input) and range (output); types of functions include linear, quadratic, and exponential.
• Trigonometric ratios (sine, cosine, tangent) relate angles to side lengths in right triangles; identities like sin²θ + cos²θ = 1 are fundamental.
• Algebra involves manipulating symbols and expressions; polynomials have terms with non-negative integer exponents; quadratic equations can be solved using the quadratic formula.
• Measures of central tendency include mean (average), median (middle value), and mode (most frequent value), essential for statistical analysis.
• Basic probability revolves around the likelihood of events; fundamental theorems include the addition rule and multiplication rule.

Computer Science

• Hardware refers to the physical components of a computer, while software is the set of instructions and programs that run on hardware.
• Basic computer architecture includes the central processing unit (CPU), memory (RAM), and input/output devices, forming the backbone of computing functions.
• Programming languages like Python and Java facilitate software development; key concepts include syntax (rules of writing code), loops (repeated execution of code), and conditional statements (if-else logic).
• Data management involves organizing and storing data in databases; SQL (Structured Query Language) is used for querying and manipulating data.
• Networking encompasses connecting computers for communication; internet protocols like TCP/IP are essential for data transfer.
• Cybersecurity involves protecting systems and data from threats, emphasizing the importance of secure practices and awareness.
