Question
- A. Resultant force equals mass times acceleration — misconception focus for Newton's second law
- B. This confuses mass and weight 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: Resultant force equals mass times acceleration — misconception focus for Newton's second law
Explanation
The correct option is Resultant force equals mass times acceleration — misconception focus for Newton's second law. Resultant force equals mass times acceleration — misconception focus for Newton's second law is correct because it matches the approved learning objective to use Newton's second law as resultant force = mass x acceleration. 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 mass and weight, omit the required force or motion condition, or move away from the exact subtopic being tested.
Common mistake
Misunderstanding Newton's Second Law
Students often confuse the relationship in Newton's second law, thinking that resultant force and mass are interchangeable rather than understanding that resultant force is the product of mass and acceleration.
To fix this, students should practice rearranging the equation F = ma to isolate each variable and understand how changing one affects the others. They should also work on problems that require them to calculate resultant force, mass, and acceleration separately.
