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.

What do you call it when an objects velocity changes?

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 a change in speed or?

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.


What is the objects change in speed called?

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.


What is term used to describe the rate of an objects movement?

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.


What is the difference an objects speed and an objects velocity?

Speed only tells how fast something is going, while velocity tells speed and direction.


What change in velocity?

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.


How does a change in speed change velocity?

due to acceleration the speed and velocity will change automatically


What happens to an objects speed if it travels with zero acceleration?

If an object travels with zero acceleration, its speed remains constant. This means that the object maintains the same speed throughout its motion and does not change its velocity.


What term used to describe the rate of an objects movement?

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.


Is a change in speed a change in velocity?

Yes, a change in speed can also be a change in velocity if the direction of the object's motion also changes. Velocity is a vector quantity that includes both speed and direction, so any change in speed or direction will result in a change in velocity.


Can a change in velocity always indicate a change in speed?

Velocity has direction as well as magnitude. Speed only has magnitude. So the velocity of something can change without its speed changing. This is what is happening when something is going in a circle.


The rate at which an object changes position is called what?

A change in position in a certain amount of time is called motion.
