What examiners said
The idea that tyre A exerted the greater pressure because there was a smaller area in contact with the road was very often recognised. Most candidates missed the fact that the force exerted on both tyres due to the weight of the motorcycle was the same. Common mistakes included the suggestions that the answer would be tyre B because it had a greater area in contact, and ideas based on the mass of...
— Examiner report, May/June 2025, 0653/41 Q8(a)(i) (Cambridge)
There were many correct references to the collisions of particles with the wall of the tyre. Only some candidates then explained that this causes a force and that pressure is defined as force ÷ area. Many answers described collisions between particles but omitted to include wall collisions.
— Examiner report, May/June 2025, 0653/41 Q8(a)(ii) (Cambridge)
Most candidates knew that forces between particles decrease when liquid water becomes steam. A common error was to describe how particles gain energy and move further apart with no reference to forces.
