Summary

• Description:

  The PDF document comprises SUKELLEMO JOINT PREMOCK 1 Physics Paper 3 2024 Mock Exam with Answers (Marking Scheme). The marking scheme is in a different document.

  It was a KCSE Physics 232/3 examination.

  This practical examination tests candidates' hands-on experimental proficiency, data collection accuracy, graphical analysis, and error minimization. It covers key laboratory competencies across mechanics, optics, and current electricity, preparing students for practical success in the KCSE examination.

  • Duration: 2 1/2 Hours
  • Total Marks: 40
  • Number of Questions: 2 (Questions 1 - 2)
  • Structure: The paper consists of two compulsory experimental questions: Question 1 (20 marks) on mechanics, upthrust, and fluid density; and Question 2 (20 marks) split into Part I (Optics/focal length, 7 marks) and Part II (Current electricity/resistivity, 13 marks).

  It covers the following topics:

  • Determination of solid volume via displacement and center of gravity of a meter rule
  • Principle of moments applied to immersed masses, apparent weight, and upthrust
  • Graphical analysis of balancing lengths and calculation of liquid density
  • Geometrical optics: lens magnification method, real image focusing, and focal length determination
  • Current electricity: circuit assembly, potentiometer-style length adjustment, and current measurement
  • Graphical determination of electrical resistance relationships and wire resistivity constants
  • Precision measurement of wire diameter using a micrometer screw gauge
