  It was a KCSE Physics 232/3 examination.

  This practical paper evaluates hands-on laboratory proficiencies, data recording accuracy, graphical analysis, and experimental deduction in mechanics, fluid statics, current electricity, and geometrical optics. It provides students with vital preparation for KCSE Physics practical assessments.

  • Month Administered: July 2026
  • Duration: 2 ½ Hours
  • Total Marks: 40
  • Number of Questions: 2 (Question 1 and Question 2)
  • Structure: The paper consists of two compulsory practical questions: Question 1 (20 marks) focusing on mechanics and fluid statics, and Question 2 divided into Part A (16 marks) on current electricity and Part B (4 marks) on geometrical optics.

    • Application of the principle of moments using a pivoted meter rule and a standard mass
    • Experimental determination of upthrust, density of glass rods, and relative density of liquids
  • Question 2 Part A (Current Electricity & Circuitry):
    • Measurement of wire diameter using a micrometer screw gauge
    • Investigation of electromotive force (e.m.f.), potential difference, and current flow in a nichrome wire circuit
    • Graphical plotting and analysis of electrical power against resistance wire length
    • Determination of internal resistance of a dry cell and resistivity of a conducting wire
  • Question 2 Part B (Geometrical Optics):
    • Focal length determination of a convex (converging) lens using object-screen displacement methods with real candle flame images
