Speed is how fast something is going when the direction in which it is travelling is unimportant.
Velocity is a measurement of the rate at which an object is changing its position. As such, in order to measure it, one must define both the speed at which an object is moving, and also the direction of movement.
What else can I help you with?
Do velocity describe both speed and time?
Velocity only describes speed and direction, while speed alone describes the rate of motion of an object without considering direction. Time is not directly a part of the definition of velocity, but it is a factor in determining the displacement traveled at a certain velocity.
Is it possible for an object moving in constant velocity having varying speed justify your answer?
No, it isn't possible. Velocity specifies both speed and direction; if velocity doesn't change, that means that neither the speed nor the direction change.
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.
As long as an object travels in a straight line at a steady speed it velocity is what?
If an object travels in a straight line at a steady speed, its velocity remains constant. The velocity in this case would be the speed of the object in a specified direction, which does not change over time.
What is the scientific definition of wave velocity?
Wave velocity is the speed at which a wave travels through a medium. It is determined by the frequency and wavelength of the wave, following the equation velocity = frequency x wavelength.
How is increasing speed acceleration?
By definition acceleration is the change in velocity (speed).
What is the definition velocity?
Speed plus the direction of travel.
Can an object acceleration if its velocity is constant?
No. It is a matter of definition. Acceleration is defined as a change of velocity. Technically, one must distinguish between velocity and speed. Velocity is a vector and includes the information about the magnitude (speed)and direction. One can have a constant speed and an acceleration (as in circular motion) but, by definition, constant velocity means zero acceleration.
What is the speed and direction at which something moves?
That's the definition of its velocity vector.
What is the definition of high speed?
Meaning something that goes at extreme velocity.
What is the definition of speed of an object and specification of its direction of motion?
If the speed of an object is cited and its direction of motion is also cited, we have the velocity of the object. Velocity is speed plus a direction vector.
Can wind have speed?
Wind is simply the movement of air. By definition, this movement has velocity (it has speed plus a direction).
What the definitioin of speed?
The definition of speed is the size/magnitude/measure of an object's velocity. Average speed = distance divided by time
Why there's a change velocity if you are changing direction?
Because that's the definition of 'velocity'.'Velocity' is not just a word you use instead of 'speed' when you want to sound smart.It's meaning is different from the meaning of 'speed'.'Velocity' has two parts to it . . . speed and direction. If either of those changes, thenthe velocity has changed.
Do velocity describe both speed and time?
Velocity only describes speed and direction, while speed alone describes the rate of motion of an object without considering direction. Time is not directly a part of the definition of velocity, but it is a factor in determining the displacement traveled at a certain velocity.

No, it isn't possible. Velocity specifies both speed and direction; if velocity doesn't change, that means that neither the speed nor the direction change.
What is the definition of accerlation?
Rate of change of velocity.i think you mean 'acceleration'anyway here's the definition--noun1.the act of accelerating; increase of speed or velocity.2.a change in velocity.3.Mechanics . the time rate of change of velocity with respect to magnitude or direction; the derivative of velocity with respect to time.
