Summary

• Description:

  The MS Word document comprises Mumias West Sub-County Joint Evaluation Physics Paper 1 May 2026 Pre-Mock Exam with Marking Scheme. The marking scheme is in a different document.

  It was a KCSE Physics Paper 1 examination. This paper tests candidates' conceptual and applied understanding of mechanics, properties of matter, thermal physics, and fluid dynamics through short-answer questions in Section A and structured problem-solving questions in Section B.

  • Month Administered: May 2026
  • Duration: 2 hours
  • Total Marks: 80
  • Number of Questions: 18 (Questions 1–13 in Section A; Questions 14–18 in Section B)

  It covers the following topics:

  • Section A
    • Mass as a constant quantity; weight variation from equator to poles
    • Hydraulic machines — pressure transmission and force expression
    • Diffusion of gases — comparing rates (hydrogen vs. air)
    • Intermolecular spacing — volume of water–alcohol mixture
    • Thermal expansion — expansion loops in steam pipes
    • Heating elements — nichrome wire properties; convection in kettles
    • Moments and equilibrium — spring balance reading for a pivoted metal bar
    • Force pump vs. lift pump advantage
    • Bicycle pump operation during backstroke
    • Capillarity — why water rises higher in a narrower tube
  • Section B
    • Structured problems on mechanics (moments, hydraulics, pressure in fluids)
    • Thermal physics (heat transfer, expansion, thermometry)
    • Properties of matter (surface tension, viscosity, molecular forces)
    • Wave motion and light
