4 Force & Motion questions from real MDCAT past papers (2020), each with the correct answer and a written explanation.
Under what condition an object will have zero displacement but non zero distance?
Explanation
In circular motion, after one full revolution the object returns to its starting point so displacement (vector from start to end) is zero while the distance travelled is the circumference (non-zero). Linear or random motion need not return to the start.

Force & Motion 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 Force & Motion”. What the archive can tell you is what actually appeared: 4 Force & Motion 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.
