9th Class Physics Notes 2026: Chapter-Wise PDF Download (Urdu and English Medium)
Physics in class 9 rewards students who keep up chapter by chapter. Kinematics builds on Chapter 1, and Dynamics builds on Kinematics. So the sensible way to study is one chapter at a time, and that is how this page is set up. Pick a chapter, pick your medium, and download.
These notes follow the Punjab Textbook Board (PTB) 9th class physics book used by BISE Lahore, Gujranwala, Faisalabad, Rawalpindi, Multan, Sargodha, Bahawalpur and DG Khan.

What Are Included in 9th Class Physics Notes?
These 9th Class Physics notes cover chapter-wise concepts, important formulas, numericals, short questions, long questions and exam-focused preparation for Punjab Board students.
What Each Chapter Covers
9th Class Physics Chapter 1 Notes: Physical Quantities and Measurements
The first chapter is the foundation for everything after it. It covers physical quantities, SI units, measuring instruments, significant figures and errors. Numericals in later chapters lean on these units, so it pays to get this one solid.
9th Class Physics Chapter 2 Notes: Kinematics
This chapter is about describing motion. Expect speed, velocity, acceleration, and reading distance-time and velocity-time graphs. Many students find graphs the trickiest part, so practise a few by hand.
9th Class Physics Chapter 3 Notes: Dynamics
Where Kinematics describes motion, Dynamics asks why it happens. Force, mass, momentum and Newton's laws of motion sit at the centre, along with their everyday applications.
9th Class Physics Chapter 4 Notes: Turning Effects of Forces
Moment of a force, torque and equilibrium. It's a short chapter, but the definitions have to be precise.
9th Class Physics Chapter 5 Notes: Work, Energy and Power
Work done, kinetic and potential energy, power, and how energy changes form.
9th Class Physics Chapter 6 Notes: Mechanical Properties of Matter
Density, pressure and elasticity, or how matter behaves under force.
Chapters 7 to 9
Thermal Properties of Matter covers temperature, heat and thermal expansion. Magnetism covers magnets, magnetic fields and their effects. Nature of Science covers scientific method, inquiry, observation and evidence.
Urdu Medium or English Medium: Which Should You Use?
Use the medium your board paper is set in. Exam terms such as "displacement", "torque" and "momentum" appear in English in both mediums, so students who study in Urdu should still learn the English terms. Both versions are provided so you can compare the two.
How to Study Physics Notes for Board Exams
- Read one chapter's notes, then close the PDF and write down the key definitions from memory.
- Work through the numericals yourself before checking any answer.
- Revise formulas with their units, since a missing unit costs marks.
- Return to Chapter 1 (units and measurement) whenever a numerical goes wrong.
