Question
- A. An object at rest will remain at rest unless acted upon by a net force — calculation focus for Newton's first law
- 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: An object at rest will remain at rest unless acted upon by a net force — calculation focus for Newton's first law
Explanation
The correct option is An object at rest will remain at rest unless acted upon by a net force — calculation focus for Newton's first law. An object at rest will remain at rest unless acted upon by a net force — calculation focus for Newton's first law is correct because it matches the approved learning objective to state Newton's first law in terms of motion remaining unchanged when resultant force is zero. 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
Misunderstanding Newton's First Law
Students often state that an object will always remain at rest unless acted upon by a force, neglecting that it can also continue moving at constant velocity when no resultant force acts.
Clarify that Newton's first law states that an object will remain at rest or continue to move at a constant velocity unless acted upon by a resultant force, emphasizing both scenarios.
