0is moves with a constant velocity in the positive direction......

Because that is the definition of velocity

Decrease in of velocity

No. The definition of 'acceleratiion' is 'any change in velocity'.

Zero, by definition. "Terminal velocity" implies that the velocity no longer changes.

No, velocity is by definition just a rate of movement that is a scalar quantity.

No. The definition of acceleration is change in velocity.

Average velocity is the distance traveled divided by the time it takes to travel that distance. Average velocity is also called "velocity".

Speed and acceleration.

average velocity means change in displacement and time interval ratio is called as average velocity average velocity what is the velocity at particular instant of time

Velocity can only be measured in relation to some specified point of rest, so there is no such thing as absolute velocity. All velocity is relative.

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.

In physics, velocity is the measurement of the rate and direction of change in the position of an object.

The rate of change in velocity in given time. By Suraj Kumar

The official definition for the word group velocity is "the speed at which the energy of a wave travels."

The definition of acceleration is: Any change of velocity, that is, speed or direction of motion. If an object is undergoing constant acceleration, then the definition says that its velocity must be changing.

That's the definition of 'acceleration'.

Deceleration or negative acceleration.

Speed plus the direction of travel.

The definition of velocity is the speed of something in a given direction. Therefore it's related to speed.

When the velocity stops changing, then, by definition, the acceleration is zero.

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.

Of course, velocity is a derived quantity. By definition, velocity is time rate of change of velocity. ie, Velocity = Displacement (s) / Time (t), where S and t are fundamental quantities. Hence velocity is a derived quantity.

Definition of velocity (assuming constant velocity): v = d/t. Solving for time: t = d/v (i.e., distance / velocity).

The speed of something in a given direction.
