Cambridge IGCSE Physics 0625 · 2026–2028 v2 · Original learning materials.
The moment of a force as a measure of its turning effect, with everyday examples (1.5.2.1); moment = force × perpendicular distance from the pivot (1.5.2.2); the principle of moments with one force each side of the pivot, including balancing a beam (1.5.2.3); no resultant force and no resultant moment means equilibrium (1.5.2.4); Supplement: the principle of moments with more than one force each side (1.5.2.5) and an experiment to show there is no resultant moment on an object in equilibrium (1.5.2.6); centre of gravity (1.5.3.1), finding it for an irregular plane lamina (1.5.3.2) and its effect on stability (1.5.3.3). Couples, torque by name, forces at an angle and levers as machines are not used. Resultant forces are in Resultant force, momentum in Momentum and collisions, and pressure in Pressure.
Apparatus, amounts and times in the experiment are illustrative. Real practical work follows a teacher-approved safety method.
