Summary

• Description:

  The MS Word document comprises Starehe Girls’ Centre Physics Paper 2 2025 Mock Exam with Marking Scheme. The PDF version is also available upon your request. The marking scheme is in a different document.

  The exam paper consists of two sections (Section A and Section B) and is marked out of a total of 80 marks. It should be completed by learners within a duration of 2 hours.

  The paper is intended for Form 4 learners and assesses understanding and application of electricity, magnetism, waves, and modern physics concepts through structured questions and calculations in line with the KCSE Physics syllabus.

  It covers the following topics:

  • Electromagnetic spectrum and applications
  • Reflection in mirrors and ray diagram construction
  • Magnetic fields and force on a current-carrying conductor
  • Domestic electricity, fuses, and power calculations
  • Transformers and voltage ratio calculations
  • Snell’s law and refraction of waves
  • Light-dependent resistors and variation of potential difference
  • Magnetization by stroking and polarity identification
  • Sound waves and echo sounding
  • Electrostatics and electroscope charging
  • Radioactivity and Geiger-Muller tube operation
  • Semiconductors, PN junction diode rectification, and CRO output signals
  • Cathode ray tube components and CRO measurements (frequency and peak-to-peak voltage)
  • Photoelectric effect and factors affecting electron emission
  • Resistor networks, effective resistance, and internal resistance of a cell
  • Capacitance, capacitor combinations, energy storage, and voltage distribution

  Section A contains short structured questions testing core concepts and interpretations, while Section B comprises longer questions requiring detailed explanations, accurate calculations, and clear working throughout.
