This paper  covers the following topics:

• Section A
  • Reflection of light — plane mirrors at angles
  • Concave mirrors — image characteristics
  • Lenses — diverging lens (principal focus), convex lens (real image formation, magnification)
  • Eye defects — identification, causes, and correction
  • Ideal gas and absolute zero temperature
  • Angular velocity — definition and SI unit
  • Pressure Law of gases
• Section B
  • Floatation — law of floatation, Archimedes’ principle, buoyancy calculations
  • Fluid mechanics — upthrust, tension in submerged objects, density calculations
  • Circular motion — centripetal force, angular velocity, periodic time, tension in a string
  • Optics — converging lens applications, real vs. virtual images, human eye vs. camera
  • Hydrometer — design and scale calibration
  • Gas laws — Boyle’s Law, Pressure Law, applications to car tyres and closed tubes
