Since speed is the magnitude component of the vector quantity of velocity, of course when speed changes velocity also changes.
Speed is a one dimensional scalar quantity.
Velocity is a three dimensional vector quantity describing both speed and direction of motion.
A change in an objects velocity is called acceleration. Velocity is defined as an objects speed of travel AND its direction of travel. Acceleration can change only an objects speed, only its direction or both. If there is no acceleration acting on the object, then the velocity remains constant.
Acceleration is the change in an ogjects speed or a change in an objects direction of motion or both of these. If instead of speed you use the word velocity , which is both an object's speed and its direction of motion, then you could say "acceleration is the change in an objects velocity" and that would cover all the possibilities in one statement.
Objects that do not speed up, slow down, or change it's direction unless they are pulled in some kind of way can change velocity.
Its called VELOCITY.
Velocity also includes direction.

That's simply called a change in velocity. On the other hand, the rate of change in velocity - how quickly velocity changes - is called acceleration.
That means, of course, that the velocity (and the speed) doesn't change.
Speed only tells how fast something is going, while velocity tells speed and direction.
Its called VELOCITY.
Velocity also includes direction.
Velocity will always change in speed.
Speed is the rate of movement in any direction based on change in position for a change in time. Velocity is a change in speed. It is also a change in direction while the speed does not have to change.

due to acceleration the speed and velocity will change automatically
