Speed is a scalar value and can be thought of as the rate at which an object covers distances. it's how much distance is travelled within a certain amount of time.
Velocity is a vectorial component and is defined by how fast an object changes position and by the direction of motion.
So, let's consider a person moving one step forward then one step backward. this motion results in a zero velocity since the position isn't being changed.(this example is only applicable on a specific sampling rate)
Conclusion: It's not necessary that the velocity changes when speed changes, it depends on the motion pattern. But in most cases velocity changes with speed but in some very special conditions it may remain still.

Velocity is the change of speed andor direction of an object?
Not exactly. Velocity is the speed and direction of an object's motion.If either speed or direction changes, then the change is the object's 'acceleration'.
If the instantaneous velocity of an object remains constand can its instantaneous speed change?
No. Speed can remain constant when velocity changes, but velocity can't remain constant when speed changes.
How do speed and velocity relate to acceleration?
Acceleration refers to the rate of change of velocity - how quickly velocity changes. In symbols: dv/dt. When the velocity changes, the speed may, or may not, change. For example, if an object moves in a circle at a uniform speed, its velocity is changing, but its speed is not.
Velocity is the change of speed and direction of an object?
No. Velocity is the present speed and direction of motion.If speed or direction changes, then that's 'acceleration'.
Why the speed of an object is constant while the velocity is not?
This is not always the case. But if an object moves in a circle, at constant speed, its velocity will change. Velocity is a vector - consisting of the magnitude (the speed), and a direction. So by definition, if the direction changes, the velocity changes - you have a different vector.
When does the speed of an object change?
An object's speed changes whenever the rate of change between the distance the object travels and the time it takes to travel that distance changes. Do not confuse speed with velocity; speed is scalar, and velocity is vector. Velocity can change when speed remains constant.
Does the speed of an object change?
An object's speed changes whenever the rate of change between the distance the object travels and the time it takes to travel that distance changes. Do not confuse speed with velocity; speed is scalar, and velocity is vector. Velocity can change when speed remains constant.
When an object's speed changes does it's velocity also change?
yes, speed is velocity with a direction
Velocity is the change of speed andor direction of an object?
Not exactly. Velocity is the speed and direction of an object's motion.If either speed or direction changes, then the change is the object's 'acceleration'.
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.
If the instantaneous velocity of an object remains constand can its instantaneous speed change?
No. Speed can remain constant when velocity changes, but velocity can't remain constant when speed changes.
Does speed change with velocity?
If the velocity changes, the speed may, or may not, change. The velocity can be thought of as having two components: a speed, and a direction. It is possible to change only the direction, for example, when an object moves in a circle at a constant speed. In this case, the velocity changes, but the speed does not.
Can velocity of a body vary if speed of the body change?
velocity means speed of an object and in a definite direction.That shows velocity changes with speed
Velocity is the change of speed and/or direction of an object?
FALSE. Acceleration is the change of speed and/or direction of an object.
