How Work & Energy is examined
Work & Energy sits in the official PMDC Physics curriculum, the document that defines what can and cannot appear in the 2026 paper. Everything on this page is tagged against that curriculum rather than against a chapter list invented for a website, which is why a chapter here matches the chapter your textbook and your teacher use.
Physics carries 36 of the 180 questions in the real paper - 20% of your MDCAT score, and the MDCAT is half your merit aggregate. PMDC does not publish how those 36questions are split across chapters, so no honest page can tell you “expect four from Work & Energy”. What the archive can tell you is what actually appeared: 3 Work & Energy questions out of the 37 Physics questions digitised so far.
Work through them with the explanations rather than checking answer letters. The explanation says why the other three options are wrong, and distractors get reused across years far more reliably than whole questions do.
Frequently asked questions
How many Work & Energy MCQs are on this page?
3, drawn from one past paper - the 2020 paper. Every one is transcribed from the real paper rather than written to look like a past paper question, and each carries the correct answer with a written explanation. 0 of them are readable in full without an account.
Is Work & Energy in the MDCAT 2026 syllabus?
Yes. Work & Energy is a chapter of the official PMDC Physics curriculum, and PMDC has confirmed the 2026 syllabus is unchanged from the 2025 revision, so everything on this page is still examinable.
How many Work & Energy questions come up in the MDCAT?
PMDC does not publish a per-chapter breakdown, so nobody can tell you a reliable number - be careful with pages that do. What can be counted is the paper as a whole: Physics is 36 of the 180 questions, and 8% of the Physics questions in our archive so far have come from Work & Energy.
Do these Work & Energy MCQs come with explanations?
Yes, and they are written from scratch rather than copied. An answer letter tells you nothing about why the other three options are wrong, which is the part that transfers to the next question. The first 0 questions of every paper are free to read in full; the rest need a pass.
