- A. 18 J
- B. A distractor that confuses Changes in energy with a different Energy idea
- C. A distractor that ignores calculate elastic potential energy stored
- D. A distractor that uses the wrong unit or relationship for this question
Answer
18 J
Explanation
The correct option is "18 J". 18 J is right because it answers the Changes in energy objective: Calculate elastic potential energy stored in a stretched spring within its limit of proportionality.. The distractors are incorrect because they either use the wrong Physics quantity, confuse an energy store with a transfer, or ignore the wording of this question.
Common mistake
Misunderstanding Elastic Potential Energy Calculation
Students often confuse the elastic potential energy formula Ee = 0.5 x k x e^2 by misidentifying the spring constant (k) and extension (e).
Ensure to correctly identify k as the spring constant in N/m and e as the extension in meters before substituting values into the formula.
