Question
- A. 100 J
- B. A distractor that confuses Changes in energy with a different Energy idea
- C. A distractor that ignores rearrange energy equations to find
- D. A distractor that uses the wrong unit or relationship for this question
Answer
100 J
Explanation
The correct option is "100 J". 100 J is right because it answers the Changes in energy objective: Rearrange energy equations to find mass, speed, spring constant, extension, gravitational field strength or height where appropriate.. 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
Common Mistake in Rearranging Equations
Students often confuse the variables when rearranging energy equations, leading to incorrect calculations of mass or height.
To fix this, carefully identify each variable in the equation and ensure you understand the relationships between them before rearranging.
