Physics 0625 — Paper 2
Explain the relationship between velocity and kinetic energy.

Velocity is directly proportional to kinetic energy. When velocity increases, kinetic energy increases too.

KE = ½mv² so as v goes up, KE goes up.

Example: a car moving faster has more kinetic energy.
3 / 5 Partial credit
Failed to state KE = ½mv² in formal form
"Directly proportional" is imprecise — KE varies as v²
Correctly linked KE to velocity relationship
Add: "Kinetic energy is proportional to the square of velocity" and show the formal equation.
How it works

Three steps from answer to insight

01

Select your subject & paper

Pick from 198 Cambridge subjects. Choose the paper variant, session and year. The AI loads the mark scheme alongside the question.

02

Paste or upload your answer

Type your response or upload a PDF. The AI extracts your answer, compares it against examiner expectations, and scores every point.

03

Get mark-scheme-aligned feedback

See exactly which marks you earned, which you missed, and why. Each point is traced back to the mark scheme — no guesswork, no generic feedback.

Every Cambridge subject.
One workspace.

No switching tools, no copying mark schemes by hand. CAIExaminer ships with the full Cambridge subject registry — all codes, all levels, all in one place.

"Knowing a subject and writing what the examiner wants to see are two different skills. One is about understanding — the other is about practice. You can't practice without feedback. And feedback without a mark scheme is just noise."

Why CAIExaminer exists

Every year, millions of Cambridge students sit exams they were never taught to answer. They understand the material. They study the content. But when they write an exam answer, something goes wrong — wrong command word, wrong structure, wrong level of detail.

Teachers don't have time to mark every past paper. Tutors are expensive. Generic AI tools give explanations, not examiner feedback. Students practice blind.

CAIExaminer was built to close that gap. Not to replace teachers or tutors — to give students a way to practice between lessons, check their answers against real mark schemes, and arrive at the exam room knowing exactly what the examiner wants to see.

The exam room is not where you learn.
It's where you prove what you've already learned.

CAIExaminer makes sure you walk in ready.
