Question
Explain how an object can accelerate when its direction changes, even if its speed remains constant.
Answer
An object can accelerate when its direction changes because acceleration is defined as the rate of change of velocity, which includes both speed and direction. For example, a car turning around a curve maintains a constant speed but its direction is changing, resulting in acceleration.
Explanation
This question tests the understanding of acceleration as a vector quantity that encompasses both speed and direction. It challenges students to apply their knowledge of motion concepts and the definition of acceleration.
Common mistake
Misunderstanding Acceleration
Students often think that acceleration only occurs when an object speeds up, ignoring changes in direction.
Emphasize that acceleration occurs whenever there is a change in velocity, which includes changes in direction, even if speed remains constant.
