A pendulum bob passes a marker under its lowest point moving to the right. Which of these is one complete oscillation? Then say why the marker is put at the lowest point and not at the end of the swing.

Choose one answera.From the marker moving right to the far right end of the swingb.From the marker moving right to the next pass of the marker, moving leftc.From the marker moving right until it next passes the marker moving rightd.From the right end of the swing to the left end

Cambridge IGCSE Physics 0625 · 2026–2028 v2 · Original learning materials.

Using rulers and measuring cylinders to find a length or a volume (1.1.1), measuring time intervals with clocks and digital timers (1.1.2), and finding the average of a small distance and a short time by measuring multiples, including the period of a pendulum (1.1.3), with the practical skills of tables and graphs. Vectors and scalars (1.1.4–1.1.7) are in the Resultant force module.

Apparatus, amounts and times in the experiment are illustrative. Real practical work follows a teacher-approved safety method.
