  • Duration: 2 Hours
  • Total Marks: 80
  • Number of Questions: 18 (Questions 1 - 18)
  • Structure: Two sections: Section A (25 marks, Questions 1 - 13 compulsory short-answer questions) and Section B (55 marks, Questions 14 - 18 compulsory structured data-response and calculation questions).

  It covers the following topics:

  • Section A:
    • Measurement I & II (Metre rule precision, micrometer screw gauge with positive zero error)
    • Forces (Distinction between mass and weight, friction and velocity changes along smooth and rough surfaces, pressure exerted by sharp heels)
    • Particulate Nature of Matter (Molecular arrangement in solid, liquid, and gas phases, freezing/solidification)
    • Turning Effect of a Force (Principle of moments on a balanced non-uniform beam)
    • Atmospheric Pressure and Stability (Atmospheric pressure gradient and balloon expansion, stability and center of gravity when carrying luggage)
    • Thermal Physics (Thermal conductivity in water, convection currents)
    • Introduction to Physics (Branches of physics: mechanics)
    • Fluid Flow (Bernoulli's principle in a non-uniform constriction tube)
    • Density (Relative density and density bottle calculations)
  • Section B:
    • Linear Motion (Displacement and acceleration definitions, ticker-timer tape analysis, velocity and uniform acceleration computation)
    • Floating and Sinking (Law of floatation, Archimedes' principle, relative density of liquids, upthrust and string tension, hydrometer applications)
    • Circular Motion (Centripetal force, purpose of banking roads, vertical whirl dynamics, angular velocity, and string tension)
    • Gas Laws (Pressure-temperature relationship at constant volume, absolute zero concept, Charles' and Boyle's combined gas law, kinetic theory assumptions)
    • Thermal Properties and Calorimetry (Differences between boiling and evaporation, vacuum flask insulation, latent heat of fusion and vaporization, heat exchange calculations)
