Latest Class 9 Physics Notes — All Pakistan Boards
Students waste weeks copying messy answers from random sites. These notes are chapter-wise, solved, exam-focused, and board-aligned so you can study smart, not hard. They follow the official new syllabus used across Pakistan.
Physical Quantities & Measurements
SI units, base & derived quantities, significant figures, measurement errors & accuracy.
Tip: Memorize SI base units table — examiners love tiny unit mistakes.
Kinematics
Displacement vs distance, speed, velocity, acceleration, graph interpretation.
Tip: If they give a v-t graph, area under the graph = displacement. Always draw arrows.
Dynamics
Newton’s laws, free-body diagrams, friction, mass vs weight.
Tip: Make perfect FBDs — they save marks in exams.
Turning Effects of Force
Moment of a force, couple & equilibrium, simple machines.
Tip: Remember τ = F × d for torque calculations.
Work, Energy & Power
Work done, kinetic & potential energy, conservation of energy, power.
Tip: Energy is conserved — always check initial and final energy states.
Mechanical Properties
Stress & strain, Young’s modulus, Hooke’s law, viscosity & surface tension.
Tip: Hooke’s law: F = kx is fundamental for spring problems.
Thermal Properties
Heat vs temperature, specific heat capacity, thermal expansion, heat transfer.
Tip: For calorimetry, heat lost = heat gained is the key principle.
Magnetism
Magnetic fields, field lines, magnetic materials, simple experiments.
Tip: Field lines always point from North to South outside a magnet.
Nature of Science
Scientific method, experiments, hypothesis, limitations & ethics of science.
Tip: Focus on the steps of the scientific method for exam questions.
