Here are common topics tackled in Maths and Physics during Term 1 and Term 2, typically in the South African CAPS curriculum for high school: Mathematics Term 1: Algebra: Exponents, surds, equations, inequalities, algebraic fractions. Number Patterns: Arithmetic and geometric sequences and series. Functions: Linear, quadratic, exponential, hyperbolic functions, and their graphs. Analytical Geometry: Distance, midpoint, gradient, equation of a straight line. Trigonometry: Ratios, identities, reduction formulae, 2D problems. Term 2: Functions: Further analysis of graphs, transformations, inverse functions. Financial Mathematics: Simple and compound interest, depreciation, annuities (depending on grade). Differential Calculus: Limits, derivatives from first principles, rules of differentiation, tangents, turning points (Grade 12). Probability: Basic concepts, Venn diagrams, tree diagrams, mutually exclusive and independent events. Euclidean Geometry: Theorems related to lines, triangles, quadrilaterals, and circles. Physics Term 1: Mechanics: Vectors and Scalars: Definitions, resultant vectors. Kinematics: Displacement, velocity, acceleration, equations of motion, graphs of motion (1D). Newton's Laws of Motion: Forces, free-body diagrams, friction, universal gravitation. Work, Energy, and Power: Definitions, conservation of mechanical energy. Waves, Sound, and Light: Wave properties, sound characteristics, electromagnetic spectrum, reflection and refraction of light. Term 2: Electricity and Magnetism: Electrostatics: Charge, Coulomb's Law, electric fields. Electric Circuits: Ohm's Law, series and parallel circuits, power, internal resistance. Electromagnetism: Magnetic fields, motors, generators. Matter and Materials: States of matter, density, pressure, thermal properties (heat, temperature, specific heat capacity). Chemical Change: Stoichiometry, reaction rates, chemical equilibrium (often overlaps with Chemistry).
