Summary

• Description:

  The MS Word document comprises Form 3 Physics Mid Term 2 Exam 2025 with Marking Scheme. The PDF version is also available upon your request.

  The marking scheme is in a different document.

  The exam paper, titled "PHYSICS FORM 3 TERM 2 2025 MID TERM EXAMINATION" in the document, contains 13 questions (numbered 1 to 11, then a question labeled 13, followed by an unnumbered question which can be considered as 14). The exam is marked out of a total of 49 marks and should be completed by learners within a duration of 1 hour and 15 minutes.

  The topics and skills assessed in the exam include:

  • Refraction of Light:
    • Defining refraction.
    • Stating Snell's law and the laws of refraction.
    • Calculating the refractive index for light moving between two media (e.g., water to glass).
    • Calculating the angle of refraction given the angle of incidence and refractive index.
    • Analyzing diagrams of refraction at air-water and water-glass interfaces to determine angles and refractive indices.
  • Linear Momentum and Collisions:
    • Calculating recoil velocity (e.g., of a gun firing a bullet).
    • Determining the momentum of an accelerating object.
    • Solving problems involving collisions, including:
      • Calculating the common velocity of objects after impact.
      • Calculating the distance moved after impact.
      • Calculating impulsive force.
      • Calculating the change in kinetic energy during a collision.
  • Analysis of Linear Motion:
    • Analyzing data from a ticker tape timer (running at 50Hz) to find:
      • The time taken for one tick interval.
      • Velocities between different points on the tape.
      • Acceleration of the body.
  • Motion Under Gravity (Vertical Projection):
    • Stating the acceleration of an object at its maximum height when thrown vertically upwards.
    • Calculating the time taken for a vertically projected object to return to the thrower.
    • Calculating the velocity of a vertically projected object after a certain time.
    • Calculating the distance covered by a vertically projected object in a given time.
    • Calculating the maximum height reached by a vertically projected object.
