  It is a KCSE Physics Paper 3 (232/3) Practical Joint Mock Examination that was administered in July/August 2024 for Form Four candidates in Nakuru North Sub-County.

  • Duration: 2½ Hours
  • Total Marks: 40
  • Number of Questions: 2

  The paper required candidates to answer all questions and involved practical investigations, measurements, graphical analysis, and calculations based on experimental observations.

  The paper was structured as follows:

  • Question 1: Experiment involving equilibrium of a metre rule and determination of density of a salt solution using buoyancy principles.
  • Question 2: Electrical experiment involving resistance wires, potential difference measurements, and graphical determination of electrical quantities.

  It covered the following topics:

  • Determination of volume of solid objects using displacement methods
  • Finding the centre of gravity of a metre rule
  • Principles of moments and equilibrium of a beam
  • Measurement and recording of experimental data using metre rules and measuring cylinders
  • Graph plotting and interpretation of relationships between variables
  • Determination of gradients from graphs
  • Apparent weight, true weight, and upthrust in fluids
  • Calculation of density of salt solutions using buoyancy concepts
  • Measurement of diameter of resistance wires
  • Calculation of cross-sectional area of wires
  • Use of electrical circuits involving cells, resistors, and connecting wires
  • Use of jockeys and crocodile clips in resistance wire experiments
  • Recording and tabulating experimental data
  • Graphical determination of relationships between electrical quantities
  • Determination of slopes from experimental graphs
  • Application of resistance formulas to determine unknown electrical constants
