Interpretation 1: "When an speed change..."
This implies that speed changes. In this case, yes, velocity will always change if speed changes. Here's why:
* Velocity is a vector quantity, meaning it has both magnitude (speed) and direction.
* Speed is the magnitude of velocity.
So, if the speed changes, the magnitude of the velocity changes, meaning the velocity itself changes.
Interpretation 2: "When an speed change does its velocity change..."
This is a bit more nuanced. It could be interpreted to mean that a change in speed causes a change in velocity. This is not always true. While a change in speed *can* cause a change in velocity, it's not the only way. Here's why:
* Change in Direction: Even if the speed remains constant, a change in direction will change the velocity. This is because velocity is a vector, and a change in direction changes the vector.
Example: A car traveling in a circle at a constant speed is still changing velocity because its direction is constantly changing.
To summarize:
* Speed Change Always Changes Velocity: If speed changes, velocity changes.
* Direction Change Also Changes Velocity: If direction changes, velocity changes even if speed remains constant.
