Physics ICSE Class 10 Sub-Units Under Chapters

The chapters given in Class 10 ICSE Physics syllabus are further divided into sub-units. The sub-units that each chapter covers are mentioned below in the table.

1. Force, Work, Power and Energy

• Turning forces concept; moment of a force (torque); forces in equilibrium; centre of gravity (simple examples & numericals)
• Uniform circular motion (centripetal vs centrifugal force)
• Work, energy and power (W = FS cosθ, W = mgh, P = W/t, units – erg, calorie, kWh, eV, hp)
• Different types of energy (mechanical: PE = mgh, KE = ½mv² with derivations; chemical, heat, electrical, nuclear, sound, light)
• Machines as force multipliers (MA, VR, efficiency η; relation η = MA/VR; levers – 1st, 2nd, 3rd class; pulley systems – fixed, movable, block & tackle)

ICSE Class 10 Physics Exams: Preparation Tips 

To score well in ICSE Class 10 Physics, focus on a mix of concept clarity, practice, and presentation:

• Understand concepts thoroughly - Build strong basics in chapters like Force, Electricity, Light, and Heat instead of memorizing formulas.
• Practice numericals regularly - Solve different types of problems daily to improve speed and accuracy, especially from Electricity and Work & Energy.
• Focus on diagrams - Practice neat and labelled diagrams (ray diagrams, circuits, machines) as they carry marks and improve answers.
• Learn formulas and their application - Don’t just memorize, understand where and how to apply each formula correctly.
• Solve previous year papers - This helps you understand exam patterns, important questions, and improves time management.
• Give importance to practicals - Prepare your practical file properly and revise experiments, as viva and internal marks are important.
• Revise regularly - Keep revisiting key concepts, formulas, and definitions to strengthen retention.
