ICSE Class 10 Physics: Previous Year Questions Analysis — Most Repeated Topics 2026

Most Repeated Topics (Last 5 Years)

• Electricity & Electromagnetism: 30-35 marks every year — numericals on Ohm's law, resistance, power always appear
• Light & Refraction: 15-20 marks — lens formula numericals, critical angle, total internal reflection
• Force & Momentum: 10-15 marks — numerical on F=ma, conservation of momentum, impulse
• Machines: 8-10 marks — MA, VR, efficiency calculations for lever and pulley
• Sound: 5-8 marks — echo problems, v=fλ, characteristics of sound

Chapter-Wise Marks Distribution

• Force (10 marks), Work-Energy-Power (8 marks), Machines (8 marks)
• Light (15 marks), Sound (8 marks)
• Current Electricity (18 marks), Electromagnetism (10 marks)
• Heat (8 marks), Radioactivity (5 marks)

High-Priority Numericals

• Ohm's law: V=IR, series and parallel resistance — appears EVERY year
• Lens formula: 1/v - 1/u = 1/f — calculate image distance, magnification
• Momentum: F=ma, conservation of momentum in collision/explosion
• Machines: Given load and effort, find MA, VR, efficiency
• Echo: distance = speed × time / 2

Prediction for 2026

• Expect 2-3 numericals on electricity (Ohm's law, power, energy)
• One numerical each on lens formula and momentum
• Diagram-based question on motor/generator — know Fleming's rules
• Theory: differentiate AC and DC, explain electromagnetic induction
