Summary

• Description:

  The PDF document comprises STAREHE GIRLS' CENTRE Physics Paper 3 Pre Mock Exam with Answers (Marking Scheme). The marking scheme is in a different document.

  It was a Pre-mock Physics Paper 3 (Practical) examination.

  This practical paper assesses experimental skills in mechanical oscillations, Hooke's law, optical refraction through prisms, circuit wiring, resistance measurement, and precision estimation of physical dimensions. It prepares candidates for laboratory accuracy and rigorous data analysis.

  • Duration: 2 1/2 Hours
  • Total Marks: 40
  • Number of Questions: 2 (Questions 1 - 2)
  • Structure: Question 1 (20 marks) on mechanics, Hooke's law, and vertical oscillations; Question 2 (20 marks) divided into Part A (optics with a triangular glass prism) and Part B (current electricity along a mounted resistor wire and wire thickness/volume measurement).

  It covers the following topics:

  • Section A:
    • Hooke's law verification using a helical spring and pointer assembly
    • Data collection, table completion, extension vs mass graph plotting, and gradient determination
    • Simple harmonic motion (measuring periodic time of vertical oscillations and computing periodic time squared per unit mass)
  • Section B:
    • Refraction of light through a triangular glass prism using optical pins
    • Measurement of prism angle, angle of deviation, and calculation of refractive index
    • Current electricity circuit assembly with an ammeter, torch bulb, and mounted resistance wire
    • Potential difference, current variation with length, and average electrical resistance of a torch bulb
    • Linear measurement (determining wire diameter using closely wound turns on a test tube and calculating wire volume)
