Linear Motion Differentiates between kinematics and dynamics. Defines displacement, speed, velocity, and acceleration, providing formulas and worked examples for each. Covers motion graphs, including distance-time and velocity-time graphs, and explains how to interpret them to find speed, acceleration, and distance covered. Introduces the ticker-timer as a tool for analyzing motion. Lists and applies the three equations of linear motion, including their use for motion under gravity (free fall and vertical projection). Refraction of Light Defines refraction and explains the laws of refraction, including Snell’s Law. Discusses the refractive index, real and apparent depth, and the conditions for total internal reflection and the critical angle. Covers applications of total internal reflection such as in prism periscopes, binoculars, and optical fibres. Newton’s Laws of Motion States and explains Newton’s First Law (Inertia), Second Law (F=ma), and Third Law (Action-Reaction). Introduces concepts of momentum, impulse, and the law of conservation of linear momentum, with applications to collisions and rocket propulsion. Discusses friction, including the laws of friction and methods of reducing it. Energy, Work, Power, and Machines Defines energy, work, and power, providing their respective formulas and SI units. Explains the principle of conservation of energy. Introduces simple machines, defining Mechanical Advantage (M.A.), Velocity Ratio (V.R.), and efficiency. Covers various types of machines, including levers, pulley systems, the wheel and axle, the inclined plane, the screw, and hydraulic machines. Current Electricity Defines electric current and potential difference (p.d.). States Ohm’s Law (V=IR) and distinguishes between ohmic and non-ohmic conductors. Discusses factors affecting the resistance of a conductor and the concept of resistivity. Explains series and parallel combinations of resistors, providing formulas for calculating equivalent resistance. Defines electromotive force (e.m.f.) and internal resistance of a cell. Waves II Explores the properties of waves, including rectilinear propagation, reflection, refraction, diffraction, and interference (constructive and destructive). The ripple tank is mentioned as a tool to demonstrate these properties. Introduces stationary (standing) waves. Electrostatics II Describes electric fields and their representation using lines of force. Explains charge distribution on conductors and action at sharp points, leading to phenomena like corona discharge and the principle behind the lightning arrestor. Introduces capacitors, defining capacitance (C=Q/V), and discussing factors affecting capacitance and combinations of capacitors in series and parallel. Heating Effect of an Electric Current Details the factors affecting heat produced by an electric current. Provides formulas for electrical energy and power (P=VI, P=I²R). Discusses applications of the heating effect, such as in filament lamps, fluorescent lamps, electric heaters, and fuses. Quantity of Heat The Gas Laws PAGES:50 FORMAT: PDF
