Question
Explain how an object can have positive acceleration while moving in a negative direction.
Answer
An object can have positive acceleration while moving in a negative direction if its speed is increasing in that negative direction. For example, if an object is moving left (considered negative) and speeds up, it has positive acceleration.
Explanation
This question assesses the ability to apply the concept of acceleration in different contexts. A strong answer demonstrates an understanding of how direction and speed interact, showing that acceleration is not solely about the direction of motion but also about changes in speed.
Common mistake
Misunderstanding Positive Acceleration
Students often think that positive acceleration means the object is moving faster in any direction, without considering the direction of velocity.
Emphasize that positive acceleration specifically refers to an increase in velocity in the chosen direction, and clarify the importance of direction in understanding acceleration.
