Which of the following would be a change in velocity but not in speed?

Velocity is a vector quantity, i.e. it consists of two measures, one is speed, the other is direction.
If the speed remains constant then a change in direction would alter the velocity.

What are the ways that an object can accelerate?
An acceleration is any change in an object's velocity, so each of the following would be an acceleration:The speed increases.The speed decreases.The speed remains constant, but the direction changes.It is important to understand that "velocity" is a vector, consisting of a speed, and a direction.
What is the magnitude of average velocity?
Not directly. acceleration is the rate at which velocity changes, but unless near light-speed the only reason velocity would cause any difference to acceleration would be due to forces which are proportional to velocity, such as drag or friction. Near the speed of light time bends so a body would, compared to the rest of the universe, appear to decelerate so as to reach a maximum velocity of the speed of light.
How would the velocity of an object change when the speed stays the same?
Velocity includes both speed and direction, so velocity will change when an object changes direction while maintaining it's speed. An example is a car at constant speed around a curve.
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 do you need to know to determine the velocity of a moving object?
Velocity means speed and direction. If one car was travelling 60mph northwards and one car was travelling 60mph southwards, they would both have the same speed but they would have different velocities. Acceleration means a change in velocity; this could be a change in speed or direction or both.
What would have to be true for the velocity to be constant?
the speed would have to change.

When can an object a constant speed but not a constant velocity?
If the velocity is constant there is no acceleration. Speed is not velocity, velocity has speed and direction. I A car going around a circular track at 60 mph keeps the same speed but changes direction and thus accelerates at a constant speed. Velocity is speed in a certain direction. So change the speed but keep direction the same and you change the velocity. or Change the direction while keeping the speed the same and you change the velocity. If the speed is constant, any change of direction is a change in velocity. Driving around in a circle is a case of constantly changing direction.
What is speed in calculus?
Speed is an example of a rate of change. It is specifically the rate of change of distance over time.In calculus, speed is the absolute value of velocity. Velocity measures both speed and direction, while speed only measures speed. For example, if a car is driving backward with a speed of 90km/h, its velocity would be -90km/h because "backward" indicates a "negative" velocity.
Is the rate at which an object changes velocity?
No, velocity is the instantaneous speed of an object, the rate of change would be the acceleration of the object.
How would you describe the values for acceleration?
positive or negative change of velocity or change of direction of the speed vector
What does a flat line on a velocity -time graph represent?
A flat line would indicate a constant velocity, no change in speed.
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 an example of the word velocity?
Velocity means speed or speediness. When you drive a car at 55 mph, that would be it's velocity. It does have an upper limit of velocity. It can also mean the rate of change in speed. You can also look at it as the speed that gets you get up to 55 mph.
