Summary

• Description:

  The PDF document comprises the Physics Paper 3 (Practical) Kenya High School 2024 Mock Exam as a KCSE Trial Exam. The file includes the question paper for the candidate as well as the confidential instructions detailing the required apparatus.

  This practical paper consists of two compulsory questions, each worth 20 marks, to be completed within a 2 ½ hour period. The exam is designed to assess a student's ability to follow experimental procedures, take accurate measurements, record data systematically, plot and interpret graphs, and make logical conclusions from experimental results.

  The paper includes the following two experiments:

  • Question 1: Optics (Lenses). This experiment focuses on determining the properties of a convex lens. The procedure involves first estimating the focal length by focusing an image of a distant object. Subsequently, candidates set up a candle (object), the lens, and a screen on a metre rule. They are required to measure corresponding object and image distances for various positions of the candle, record the data in a table, and plot a graph to determine the focal length of the lens.
  • Question 2: Mechanics (Oscillations). This experiment investigates the relationship between the frequency of oscillation of a V-shaped wire pendulum and the angle of the 'V'. Candidates are required to bend a copper wire to specific angles, suspend it, and then measure the time taken for a set number of oscillations using a stopwatch. This process is repeated for different angles. The data is then processed and used to plot a graph of the frequency squared (f²) against the cosine of half the angle (Cos(θ/2)), from which a physical constant is determined.
