Summary

• Description:

  The MS Word document comprises the "Form 4 Physics Mid Term 2 Exam 2025 with Marking Scheme". The PDF version is also available upon your request.

  Please note that the marking scheme is in a different document.

  The exam paper, identified in the document as "PHYSICS FORM 4 JUNE 2025 MID TERM 2 EXAMINATION", instructs candidates to answer all questions in the spaces provided. It contains 6 main questions, some with multiple sub-parts.

  The exam is marked out of a total of 51 marks.

  The topics covered in this exam include:

  • Uniform Circular Motion:
    • Definitions of angular displacement, radian, and angular velocity.
    • Calculations involving periodic time, angular velocity, linear velocity, and maximum tension in a string for an object in vertical circular motion.
    • Determining the minimum velocity for a trolley at the top of a circular rail.
    • Calculating angular velocity and force exerted on rails for a trolley moving in a vertical circle.
  • Fluid Flow (Archimedes' Principle and Hydrometers):
    • Stating Archimedes' principle.
    • Calculating upthrust force on a submerged block using the principle of moments.
    • Calculating the density of a liquid.
    • Determining a new balance point when the liquid density changes.
    • Describing features and principles of a simple hydrometer: reason for a wide bulb, purpose of lead shots, how to make it more sensitive, calibration to measure relative density, and indicating minimum/maximum measurements on a diagram.
  • Optics (Lenses and The Eye):
    • Identifying eye defects based on observations (e.g., eye too short, focal length of eye lens too short implies hypermetropia).
    • Using a diagram to describe the correction of the identified eye defect.
    • Calculating the focal length of a diverging lens using the lens formula.
    • Drawing ray diagrams to locate the position of an image formed by a lens.
    • Stating similarities and differences between a camera and a human eye.
  • Electromagnetic Spectrum:
    • Naming properties common to all electromagnetic waves.
    • Calculating the wavelength of radio waves given their frequency.
    • Identifying a type of radiation (likely Ultraviolet) from its position in a given electromagnetic spectrum sequence.
