Forces and elasticity
Question
- A. 3 m — definition focus for force
- B. This confuses elastic and plastic deformation and does not answer Hooke's law and spring constant.
- 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 elasticity.
Answer
The correct answer is: 3 m — definition focus for force
Explanation
The correct option is 3 m — definition focus for force. 3 m — definition focus for force is correct because it matches the approved learning objective to calculate extension from force and spring constant. This answer belongs to Hooke's law and spring constant within Forces and elasticity, so it must use precise AQA GCSE Physics forces and motion vocabulary. The other options are wrong because they either confuse elastic and plastic deformation, omit the required force or motion condition, or move away from the exact subtopic being tested.
Common mistake
Common Mistake in Hooke's Law Calculations
Students often confuse the extension with the total length of the spring when using the formula to calculate extension.
Remember that extension is the increase in length from the original length of the spring, not the total length after the force is applied.
