 # ICSE Class 9 Physics Syllabus

ICSE Syllabus for Class 9 Physics (i.e., Science paper 1) is given here to help the Class 9 students in their preparation. The syllabus given here is detailed and is completely in accordance with the latest CISCE guidelines. Students need to check the syllabus thoroughly and prepare for their ICSE Class 9 exam accordingly.

This ICSE Syllabus of Class 9 introduces various important topics that are extremely important for later grades. Students are suggested to be thorough with all the concepts in the Class 9 Science Paper 1 (Physics) syllabus to have a strong foundation of the Physics concepts.

The latest syllabus for Class 9 ICSE Physics is given here in the below-given table.

 ICSE Class 9 Physics Syllabus (Science Paper 1) Sl. No. Chapter Name Subtopics 1. Measurements and Experimentation (i) International System of Units, the required SI units with correct symbols are given at the end of this syllabus. Other commonly used system of units – fps and cgs. (ii) Measurements using common instruments, Vernier callipers and micro-metre screw gauge for length, and simple pendulum for time. 2. Motion in One Dimension Scalar and vector quantities, distance, speed, velocity, acceleration; graphs of distance-time and speed-time; equations of uniformly accelerated motion with derivations. 3. Laws of Motion (i) Contact and non-contact forces; cgs & SI units. (ii) Newton’s First Law of Motion (qualitative discussion) introduction of the idea of inertia, mass and force (iii)Newton’s Second Law of Motion (including F=ma); weight and mass. (iv) Newton’s Third Law of Motion (qualitative discussion only); simple examples. (v) Gravitation 4.

Heat and Energy (i) Concepts of heat and temperature (ii) Anomalous expansion of water; graphs showing variation of volume and density of water with temperature in the 0 to 10°C range. Hope’s experiment and consequences of Anomalous expansion. (iii)Energy flow and its importance (iv) Energy sources. (v) Global warming and Green House effect 6. Light (i) Reflection of light; images formed by a pair of parallel and perpendicular plane mirrors(ii) Spherical mirrors; characteristics of image formed by these mirrors. Uses of concave and convex mirrors. (Only simple direct ray diagrams are required). 7. Sound (i) Nature of Sound waves. Requirement of a medium for sound waves to travel; propagation and speed in different media; comparison with speed of light. (ii) Infrasonic, sonic, ultrasonic frequencies and their applications. 8. Electricity and Magnetism (i) Simple electric circuit using an electric cell and a bulb to introduce the idea of current (including its relationship to charge); potential difference; insulators and conductors; closed and open circuits; direction of current (electron flow and conventional) (ii) Induced magnetism, Magnetic field of earth. Neutral points in magnetic fields. (iii)Introduction of electromagnet and its uses.

The topics in the Class 9 Syllabus aim to provide some basic knowledge and understanding of the important Physics terms, principles, concepts, definitions and laws. The topics here are also aimed at developing the practical, instrumental, deductive, problem-solving and observation skills of students.
