Summary

• Description:

  The MS Word document comprises Form 3 Physics Paper 3 (232/3) End Term 3 2026 Exam with Marking Scheme. The PDF version is also available upon your request. The marking scheme is in a different document.

  This practical examination tests rigorous experimental skills in electrical circuit assembly, wire resistance analysis, Hooke's law verification, and harmonic spring oscillation measurements. It is ideal for end-of-year school-based national assessment preparation towards the end of the term, and can also be effectively administered as a mid-term assessment for schools that have completed the syllabus early at the beginning of the term.

  • Duration: 2 Hours 30 Minutes
  • Total Marks: 40 Marks
  • Number of Questions: 2 Questions (1 – 2)
  • Structure: Question 1 (Current Electricity and Resistance - 20 Marks) and Question 2 (Hooke's Law and Oscillations - 20 Marks); both practical investigations compulsory

  It covers the following topics:

  • Measurement of dry cell e.m.f. and closed-circuit current across varying resistance wire lengths
  • Tabulation of current readings and reciprocal current (1/I) calculations
  • Plotting reciprocal current against wire length, gradient computation, and intercept analysis
  • Precision measurement of wire diameter using a micrometer screw gauge and cross-sectional area calculations
  • Experimental verification of Hooke's law using a vertically suspended helical spring and slotted masses
  • Extension measurement, graphing extension against mass, and slope determination
  • Measurement of periodic time for vertical harmonic oscillations under loaded masses
  • Determination of the physical constant relating spring oscillation period to the elastic force constant
