Question
- A. Forces are always equal and opposite — graph focus for Newton's third law
- B. This confuses scalar and vector quantities and does not answer Newton's laws of motion.
- C. This is too vague because it does not use the force or motion quantity named in the objective.
- D. This reverses the physical cause and effect for Forces and motion.
Answer
The correct answer is: Forces are always equal and opposite — graph focus for Newton's third law
Explanation
The correct option is Forces are always equal and opposite — graph focus for Newton's third law. Forces are always equal and opposite — graph focus for Newton's third law is correct because it matches the approved learning objective to explain Newton's third law as interacting objects exert equal and opposite forces on each other. This answer belongs to Newton's laws of motion within Forces and motion, so it must use precise AQA GCSE Physics forces and motion vocabulary. The other options are wrong because they either confuse scalar and vector quantities, omit the required force or motion condition, or move away from the exact subtopic being tested.
Common mistake
Misunderstanding Newton's Third Law
Students often think that Newton's third law means that forces cancel each other out, leading to confusion about how objects interact.
Clarify that Newton's third law states that for every action, there is an equal and opposite reaction, and these forces act on different objects, not on the same object.
