Summary

• Description:

  The MS Word document comprises Form 4 Physics Paper 3 End Term 2 2025 Exam with Marking Scheme. The PDF version is also available upon your request. The marking scheme is in a different document.

  The exam paper contains 2 practical questions and it is marked out of a total of 40 marks. Learners should complete it within a duration of 2 ½ hours.

  The practical experiments covered in this paper are:

  • Question 1 (Part A - Optics): This experiment is designed to determine the focal length of a convex lens. Students are required to set up an object, a lens, and a screen, measure various object distances (u) and corresponding image distances (v), and then plot a graph of uv against (u+v) to find the slope, which represents the focal length.
  • Question 1 (Part B - Flotation): This experiment involves determining the density of a liquid. Students use a loaded boiling tube floated in the liquid, measure its mass and dimensions (length and diameter), and apply the principle of flotation to calculate the liquid's density.
  • Question 2 (Electricity): This experiment focuses on determining the internal resistance of a battery. Students set up a circuit with a battery, voltmeter, ammeter, and a nichrome wire as a variable resistor. They measure the voltage and current for different lengths of the wire and plot a graph of (E-V) against I to determine the internal resistance from the slope.
