Here's why:
* Speed refers to how fast an object is moving.
* Direction refers to the path the object is taking.
Instantaneous velocity combines both speed and direction at a single point in time. It's the rate of change of an object's position at that specific moment.
Let's break it down:
* Velocity is a vector quantity, meaning it has both magnitude (speed) and direction.
* Instantaneous means at a particular moment in time.
Therefore, instantaneous velocity accurately describes the speed and direction of an object at a specific moment, making it the appropriate term for this question.
