  It covers the following topics:

  • Section A:
    • Thermal expansion — using temperature change to separate a metal stuck in a glass pipe
    • Density — effect of a deflated football on its density
    • Measurement — zero error and micrometer screw gauge readings (positive and negative errors)
    • Momentum and impulse — impulsive force from a collision between a car and a stationary block
    • Surface tension — explaining the shape of a water drop before and after falling from a pipette
    • Pressure — density of a liquid using a manometer, given gas and atmospheric pressures
    • Centre of gravity — balancing a V-shaped wire on a string; reasoning for ease of balancing
    • Fluid flow — Bernoulli's principle and air intake in a Bunsen burner
    • Moments — tension in a chain holding a uniform metal bar at equilibrium
    • Heat conduction — role of lead shot in a conduction experiment; identifying which wax melts first
  • Section B:
    • Projectile motion — two marbles projected horizontally from a cliff; range, vertical velocity, horizontal velocity, and shortest distance between them on landing
    • Hooke's Law experiment — two identical springs; measurements taken, graph interpretation (sections AB and CD), spring constant, work done in section CD, and sketch for a single spring
    • Inclined plane — work done against gravity and by the applied force as a trolley moves from A to B
    • Additional structured questions on thermal physics, fluid mechanics, and circular/rotational motion
