- B. In a system with high friction between moving parts
- C. In a vacuum environment
- D. In a system with no moving parts
Answer
In a system with high friction between moving parts
Explanation
The correct option is "In a system with high friction between moving parts". In a system with high friction between moving parts is right because it directly matches Energy transfers in a system: Explain how lubrication reduces unwanted energy transfers by reducing friction.. The other options are less suitable because they change the required Physics relationship, confuse the relevant energy store or use a distractor that does not answer the question.
Common mistake
Misunderstanding Lubrication
Students often think lubrication eliminates friction completely.
Explain that lubrication reduces friction but does not eliminate it entirely.
