Summary

• Description:

  The MS Word document comprises ELITE EXAMINATIONS Physics Paper 3 2026 Mock Exam with Answers (Marking Scheme). The PDF version is also available upon your request. The marking scheme is in a different document.

  It was a KCSE Physics 232/3 examination.

  This practical examination rigorously tests candidates' experimental skills, data acquisition accuracy, graphical representation, and scientific deduction in mechanics, electricity, and geometrical optics. It is an indispensable assessment tool designed to prepare Form 4 candidates for the hands-on laboratory rigor demanded in the national KCSE physics practical paper.

  • Month Administered: July, 2026
  • Duration: 2 ½ Hours
  • Total Marks: 40 Marks
  • Number of Questions: 2 Questions (Question 1 and Question 2)
  • Structure: Two compulsory practical questions carrying 20 marks each, subdivided into distinct experimental procedures.

  It covers the following topics:

  • Question 1 (Mechanics and Periodic Oscillations):
    • Part A: Investigating oscillations of a suspended wire pendulum, recording periodic times, plotting a graph of T² against length X, determining slope S, and evaluating constant k
    • Part B: Vertical oscillations of a weighted floating boiling tube in water, measuring oscillation periods, and evaluating the constant P
  • Question 2 (Current Electricity & Geometrical Optics):
    • Part A: Electrical circuit analysis using a resistance wire, measuring electromotive force (e.m.f.), recording current and potential difference variations with wire length, determining internal resistance, measuring wire diameter using a micrometer screw gauge, and calculating resistivity
    • Part B: Refraction of light through a rectangular glass block using the pin method, ray tracing, determining real and apparent depth distances, evaluating the constant k, and identifying its physical significance as the refractive index of glass
