Question
- A. They result in a net force of zero — calculation focus for distinguish
- B. This confuses resultant force and balanced forces 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: They result in a net force of zero — calculation focus for distinguish
Explanation
The correct option is They result in a net force of zero — calculation focus for distinguish. They result in a net force of zero — calculation focus for distinguish is correct because it matches the approved learning objective to distinguish Newton's third-law pairs from balanced forces acting on one object. 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 resultant force and balanced forces, omit the required force or motion condition, or move away from the exact subtopic being tested.
Common mistake
Confusing Third Law Pairs
Students often confuse Newton's third-law pairs with balanced forces acting on a single object, thinking they are the same.
To fix this, remember that third-law pairs involve two different objects exerting equal and opposite forces on each other, while balanced forces act on the same object and result in no change in motion.
