Here's a breakdown:
* Speed is a measure of how fast an object is moving. It is a scalar quantity, meaning it only has magnitude. For example, 10 meters per second (m/s).
* Acceleration is the rate at which an object's velocity changes over time. It is a vector quantity, meaning it has both magnitude and direction. For example, 5 meters per second squared (m/s²).
Accelerative speed might refer to speed increasing over time. However, it's more accurate and common to say that the object is accelerating, meaning its speed is increasing.
If you can provide more context about where you encountered the term "accelerative speed", I can help you understand its meaning more accurately.
