Summary

• Description:

  The MS Word document comprises KCSE 2026 Physics Paper 3 Prediction Paper with Answers (Set 3). The PDF version is also available upon your request. The marking scheme is in a different document.

  It was a KCSE Physics Paper 3 prediction examination designed to prepare candidates for the national assessment.

  A practical examination testing experimental competencies, graphical analysis, and data deduction across current electricity, geometrical optics, and density/volume mensuration.

  • Duration: 2½ Hours
  • Total Marks: 40
  • Number of Questions: 2 (Questions 1 - 2)
  • Structure: Practical laboratory examination comprising two compulsory 20-mark experimental questions

  It covers the following practical skills:

  • Current Electricity (Investigation of the relationship between potential difference and current across a variable length of resistance wire, circuit wiring, voltmeter-ammeter data logging, filament bulb brightness observations, voltage versus current graph plotting, slope calculation, and determination of electrical resistance)
  • Geometrical Optics - Thin Lenses (Measurement of object distance and image distance for a convex lens illuminated by a candle flame, image sharpness focusing, linear magnification calculation, and determination of the average focal length using the lens formula relation)
  • Mechanics and Mensuration (Precision measurement of truncated cone/rubber bung dimensions using Vernier calipers, mass measurement using an electronic balance, evaluation of geometric constants, and mathematical deduction of material density)
