0625_s26_ms_132026 May-June Physics 0625 Mark Scheme 1 Variant 3

This is the official Cambridge mark scheme for Physics (0625) Mark Scheme 1 (Variant 3) from the 2026 May-June session. Mark schemes show exactly how each mark is awarded, including acceptable alternative answers, required key terms, and common errors that lose marks. Cambridge mark schemes use notation like "allow," "accept," and "do not credit" to define the boundary between full marks and zero.

This mark scheme corresponds to 0625_s26_qp_13. For maximum revision benefit, attempt the question paper under strict exam conditions first, then use this mark scheme to self-assess. Pay attention to the marking notation: "allow" means an alternative is accepted, "do not credit" means a specific phrasing is rejected even if technically correct, and "ORA" (or reverse argument) means the mark can also be earned with the opposite reasoning.

Cambridge mark schemes reward precise language. For Physics (0625), look for keywords the examiner requires — definitions must include specific terms (e.g., "per unit mass," "resultant"), and calculations must show working even if the final answer is correct. Understanding mark scheme conventions helps you write answers that hit every marking point, not just the general idea.

1

Unit conversion errors — minutes to hours, kW to W, cm to m, km³ to m³

Incorrect answers chosen involved using an incorrect equation, not converting minutes to hours or not converting watts to kilowatts.Paper 1, May/June 2023

How to fix: Write every conversion: 1 hour = 60 min (not 100). 1 kW = 1000 W. 1 km = 1000 m, so 1 km³ = (1000)³ m³ = 10⁹ m³. For time: 3h 20min = 10/3 hours (not 3.20). Always convert BEFORE substituting into equations.

2

Equation rearrangement errors — dividing instead of multiplying

The most common incorrect answer was option A, indicating that candidates had not rearranged the equation correctly and instead they divided force by distance.Paper 1, May/June 2023

How to fix: Write the formula first. Then rearrange algebraically BEFORE substituting numbers. Check: if speed = distance/time, then distance = speed × time (multiply, not divide). Use the formula triangle if needed, but always verify the rearrangement makes sense.

5

Mass vs weight confusion — even at Extended level

Only stronger candidates answered this correctly, with the majority confusing weight and mass and therefore choosing option A.Paper 1, May/June 2023

How to fix: Mass = amount of matter (kg, measured with balance, same everywhere). Weight = gravitational force on an object (N, measured with newton-meter, changes with location). Weight = mass × g. An object on the Moon has the SAME mass but LESS weight.
