Summary

• Description:

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

  It was a KCSE Physics 232/1 examination.

  This paper assesses candidates' mastery of classical mechanics, fluid dynamics, thermal physics, properties of matter, and gas laws. It emphasizes mathematical precision, conceptual clarity, graph analysis, and real-world physical problem solving to ensure candidates are thoroughly prepared for the KCSE Physics Theory examination.

  • Duration: 2 Hours
  • Total Marks: 80
  • Number of Questions: 18 (Questions 1 - 18)
  • Structure: The paper is divided into two sections: Section A (25 marks) consisting of short-answer questions 1 to 12, and Section B (55 marks) containing structured questions and data analysis problems 13 to 18.

    • Hooke's law in parallel and series spring combinations
    • Principle of moments and equilibrium of uniform pivoted rods
    • Atmospheric pressure and gas pressure trapped by mercury columns
    • Fluid dynamics: continuity equation, fluid speed in narrowing pipes, and bubble expansion
    • Thermal radiation and emissivity of dull versus shiny surfaces
  • Section B:
    • Uniform circular motion: angular velocity, centripetal acceleration, tension, and linear velocity
    • Graphical analysis of angular velocity squared against inverse radius
    • Archimedes' principle, law of floatation, apparent weight, and upthrust calculations
    • Calorimetry, heat capacity, method of mixtures, and specific heat capacity of metals
    • Machines: pulley systems, velocity ratio, mechanical advantage, efficiency, and hydraulic lifts
