Question
Explain why an object can have a constant speed but still have a changing velocity.
Answer
An object can have a constant speed while its velocity changes if it is moving in a curved path. Velocity is a vector quantity, which means it has both magnitude and direction; thus, a change in direction, even at constant speed, results in a change in velocity.
Explanation
This question assesses the student's understanding of the distinction between speed and velocity, emphasizing the vector nature of velocity. It encourages critical thinking about motion in different directions.
Common mistake
Misunderstanding Speed Definition
Students often confuse speed with velocity, thinking they are the same because both involve distance and time.
Emphasize that speed is a scalar quantity that only considers distance travelled over time, while velocity is a vector quantity that includes direction.
