Question
- A. Each skater exerts an equal and opposite force on the other skater.
- B. The forces are balanced because they act on one skater.
- C. The heavier skater exerts a force but feels none.
- D. The forces cancel before either skater moves.
Answer
The correct answer is: Each skater exerts an equal and opposite force on the other skater.
Explanation
The correct option is Each skater exerts an equal and opposite force on the other skater.. This fits Acceleration in Forces and motion because it uses the named force or motion relationship in the situation, gives the correct unit or graph meaning where needed, and avoids the specific misconception in the distractors.
Common mistake
Misunderstanding Deceleration
Students often confuse negative acceleration with a decrease in speed only, without considering the direction of motion.
Emphasize that negative acceleration (deceleration) indicates a decrease in velocity in the chosen direction, and clarify that it can occur even if the object is moving forward.
