A student in Trinidad observes a maxi-taxi suddenly braking at a traffic light. The passengers lurch forward. Which of Newton's Laws best explains this observation?

Q: How do I try a free CXC Integrated Science question?

Just tap any of the four options on this page — no signup, no card, nothing to install. You'll see the correct answer and a full mark-scheme-style explanation within a second. Each visit shows a fresh randomly-picked question from the live CXC CSEC Integrated Science bank, so you can keep refreshing to try different ones before deciding whether to create a free account for daily access.

Q: Is Kramizo really free for CXC Integrated Science students?

Yes — completely free. Every student gets 45 questions a day on the free plan, across any board and any subject, with no card required and no trial countdown. Kramizo's optional Pro plan removes the daily cap and adds analytics, but the free plan is genuinely free forever. We make money from the small percentage of students who choose to upgrade — not from selling data or ads.

Q: Are the Integrated Science questions aligned to the CXC CSEC syllabus?

Every question is written against the published CXC CSEC Integrated Science syllabus and reviewed for accuracy before being added to the bank. We match the command words (state, describe, explain, evaluate), mark allocations, and difficulty tier you'll see on real CXC past papers. Explanations are written in the style of official examiner mark schemes so students learn exactly what marks are being awarded for.

Question

A student in Trinidad observes a maxi-taxi suddenly braking at a traffic light. The passengers lurch forward. Which of Newton's Laws best explains this observation?

Accepted Answer

Newton's First Law of Motion — Award 1 mark for recognising that objects continue in their state of motion unless acted upon by an external force — passengers continue moving forward when the vehicle stops. A is incorrect — gravitation deals with attraction between masses, not inertia. C is incorrect — the Second Law relates force, mass and acceleration (F = ma). D is incorrect — the Third Law concerns action-reaction pairs.

Answer

Newton's Third Law of Motion

Answer

Newton's Second Law of Motion

Answer

Newton's Law of Gravitation

Answer

Newton's First Law of Motion
