Class 9 – CBSE Board Science (Physics)

Science (Physics Component)

Based on CBSE’s Class 9 Science syllabus—which integrates physics topics including Motion, Force, Energy, etc.:

• Unit I. Matter – Its Nature and Behaviour (25 marks): States of matter, particle nature, physical/chemical changes (practicals included)
• Unit III. Motion, Force and Work (27 marks): Distance & displacement, velocity, acceleration, Newton’s laws, momentum, work, energy, power, conservation of energy
• Additional physics topics: Sound, Gravitation, Floatation

Internal Assessment (20 marks) includes practicals and other school-based evaluations
