Summary

• Description:

  The PDF document comprises THE SUPER LEAGUE JOINT NATIONAL MOCKS Physics Paper 1 2026 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 theoretical and quantitative understanding of mechanics, thermal physics, properties of matter, and fluid dynamics. It evaluates candidates' skills in physical measurements, gas law experiments, rotational dynamics, work-energy principles, and Archimedes' floatation mechanics.

  • Duration: 2 Hours
  • Total Marks: 80
  • Number of Questions: 19 (Questions 1 to 19)
  • Structure: The paper consists of two sections: Section A (25 marks) containing 14 compulsory short-answer questions (Questions 1 to 14), and Section B (55 marks) containing five compulsory extended structured and calculation questions (Questions 15 to 19).

  It covers the following topics:

  • Section A
    • Measurement and Precision (Tape measure accuracy, measuring screw thread pitch using a metre rule, micrometer screw gauge selection)
    • Pressure and Fluid Behavior (Wide tyres and surface pressure, atmospheric pressure absence on the moon)
    • Particulate Nature of Matter and Heat Transfer (Diffusion of ink in water, thermal conductivity of water in a boiling tube)
    • Capillarity and Surface Tension (Capillary rise in glass tubes of different diameters)
    • Density and Upthrust (Floating conditions of solid versus hollow copper spheres)
    • Fluid Dynamics (Bernoulli's principle and velocity-pressure variations)
    • Equilibrium and Stability (States of equilibrium: stable versus neutral)
    • Gas Laws (Boyle's law isothermal curves)
    • Circular Motion (Tangential release path of a whirled ball when string snaps)
    • Hooke's Law and Gravitational Field Strength (Spring extension comparison between Earth and Moon)
  • Section B
    • Uniform Circular Motion (Definitions of angular velocity and centripetal acceleration, spring balance on a rotating turntable, uniform angular velocity calculations)
    • Gas Laws (Pressure Law, Bourdon gauge experimental verification, Gay-Lussac pressure-temperature computations, trapped air column and mercury thread analysis)
    • Work, Energy, Power, and Simple Machines (Mechanical advantage, velocity ratio, pulley systems, load and effort analysis on a wheelbarrow, translational and rotational kinetic energy, potential vs kinetic energy graphs)
    • Floatation and Archimedes' Principle (Law of floatation, composite wood-metal floating systems, forces on tethered floating corks under rising water levels)
    • Fluid Flow (Streamline to turbulent flow transitions, equation of continuity in narrowing pipes, liquid pressure head, and efflux velocity)
