Summary

• Description:

  The MS Word document comprises Grade 10 Physics Term 3 2026 Opener Exam with Marking Scheme. The PDF version is also available upon your request. The marking scheme is in a different document.

  This assessment examines fundamental principles of introductory physics, evaluating learners' competencies in SI unit analysis, precision measurements, density, forces, fluid mechanics, thermal physics, and ray optics.

  • Duration: 2 Hours
  • Number of Questions: 18 (Questions 1–18)
  • Structure: Structured theory, numerical calculations, scale reading, and experimental analysis questions

  It covers the following topics:

  • Base SI quantities and units, vernier caliper measurements, and volumetric density calculations
  • Branches of physics, definition of force, and molecular cohesive versus adhesive forces
  • Hooke's law and spring constant determination
  • Solid pressure calculations (maximum and minimum pressure on surfaces)
  • Liquid pressure and total hydrostatic pressure at depth
  • Atmospheric pressure: mercury barometers and barometric pressure conversion to Pascals
  • Particulate nature of matter: Brownian motion observation, kinetic interpretation, and temperature effects
  • Thermal expansion: bimetallic strip behavior, practical applications, and anomalous expansion of water with graph analysis
  • Thermal energy transfer mechanisms and heat loss reduction in a vacuum flask
  • Geometrical optics: laws of reflection, plane mirror image characteristics, multiple image calculations, and periscope operation
