Summary

• Description:

  The MS Word document comprises Form 3 Physics Mid Term 2 2026 Exam with Marking Scheme. The PDF version is also available upon your request. The marking scheme is in a different document.

  This paper assesses Form 3 students on mechanics, motion, and the behaviour of springs — requiring both conceptual understanding and quantitative problem-solving that closely aligns with the KCSE Physics syllabus emphasis on application of physical laws.

  • Total Marks: 80
  • Number of Questions: 14 questions (Questions 1–14)
  • Structure: Two sections — Section A (25 marks, answer all questions), Section B (extended-response and calculation questions)

  It covers the following topics:

  • Section A
    • Machines — pulley systems, mechanical advantage, velocity ratio, and efficiency
    • Momentum calculations (matatu mass and speed context)
    • Newton's laws of motion — third law and application to collisions
    • Impulse and take-off speed (footballer kicking a ball)
    • Collapsible bumpers and the concept of impulse in car safety
  • Section B
    • Projectile motion and free fall — velocity-time graph interpretation
    • Potential energy and kinetic energy during a dive
    • Retarding force and energy losses in water
    • Springs in networks — total extension, elastic limit, and elastic potential energy
    • Friction — methods of reduction
