Velocity is a quantity that has magnitude and direction. The magnitude of velocity is what we call "speed".

If the velocity is constant, then its magnitude and direction are both constant.

Constant magnitude means constant speed.

So the answer to the question is "Yes".

If a car moves with constant speed does it also moves with constant velocity?

A car moving with a constant speed is moving with a constant velocity if and only if it is travelling along a straight line.

If A car moves at constant speed also moving at constant velocity?

Not necessarily. Constant velocity also means no change in direction.

If a car moves at constant speed also moving at constant velocity give an example?

A car moving at constant speed in a straight line is also moving at constant velocity.

What is the acceleration of an object that moves at constant velocity?

'Constant velocity' means constant speed in a straight line.That's also a good definition of zeroacceleration.

What is phase velocity?

The velocity of a point that moves with a wave at constant phase. Also known as celerity; phase speed; wave celerity; wave speed., wave velocity.

When an object moves with constant velocity what happens?

Constant velocity means that the object's speed is constant, and it moves in a straight line, i.e. the direction of its motion is also constant. When an object moves in a manner consistent with this description, probability dictates that sooner or later, it bumps into something.

Moving at constant velocity is also moving with constant speed?

Velocity is Speed in a given direction. Moving at constant velocity is equivalent to say moving with a constant speed in a specified direction. So, moving at constant velocity implicitly means moving with constant speed.

When can an object a constant speed but not a constant velocity?

Consider an object turning in a circle at a constant speed. Because velocity is not just the value of speed, but also the direction in which the object is moving, the velocity would not be constant.

Can a body have constant velocity when it has constant speed?

Of course. In fact, in order to have constant velocity, it must have constant speed.What you really want to know: Can a body have changing velocity when it has constant speed ?The answer to that one is also "yes", for example when it is moving in a circle, the speed is constant but the velocity is changing all the time (in direction).

Can an object have a varying speed if its velocity is constant?

No, velocity is a vector quantity and measures both speed and direction. If the velocity of an object is constant then that would also mean the speed would stay constant.

If a car moves with a constant speed does it also moves with a constant velocity?

Not necessarily.Speed is a scalar measurement that only measures magnitude.Velocity, on the other hand, is a vector measurement and adds the important distinction of a direction.A car rounding a curve may be going the same speed, but its velocity is constantly changing throughout the curve because its direction keeps changing.

Can an object have a constant spped and velocity at the same time?

Velocity is a vector quantity. That means it has direction and magnitude. Speed is a scalar quantity, it only has magnitude. It is possible to have constant speed and constant velocity but it is also possible to have constant speed but changing velocity if the object is changing direction.

What is the difference between constant speed and speed?

Constant speed is constant velocity which means your going a certain speed in a straight line. Speed is just your speed at an exact moment also called instantaneous speed

If the speed of a body remaining same discuss wheather its velocity can change?

Yes; if the direction changes (for instance, if an object moves in a circle), even if its speed doesn't change, its velocity changes. This is because the term "velocity" also includes the direction.

Can the velocity of a car which is turning a curve be held constant?

The speed can be constant but the velocity can't, because the directionof motion ... which is a component of velocity ... is changing. Also the velocity of a moving body changes when its speed changes but remains moving towards the same direction ... :) :]

What happens to the forces of an object when it reaches a constant speed?

At constant speed the forces could be zero if velocity is also constant, otherwise the force will be f=ma where a is not zero.

The velocity of an object can what if the speed of an object remains constant?

The velocity can still change, even if the speed doesn't. This is because velocity is a vector - not only the magnitude is important, but also the direction.

Is it true that Velocity is the speed of the wave?

In common language, the terms "velocity" and "speed" are used interchangeably. In physics, "velocity" is a vector, and "speed" is not - meaning that when the word "velocity" is used, it specifies not just how fast something moves, but also in what direction.

What is uniform velocity?

A body is said to move with uniform velocity if it has no acceleration. This implies that the body moves with a constant speed along a straight line path. This also means that the body moves with equal displacements in equal intervals of time, however small these time intervals may be.

Does the instantaneous speed ever equal the magnitude of its average velocity?

Yes. For a start, this happens when the object moves at a constant velocity. Also, if moving in a straight line, even if the object changes speed there must needs be a moment when its instantaneous speed is equal to its average speed - since it cannot change speed suddenly, it must do so gradually.

Is a car on a circular track has also constant velocity?

Yes, IF it maintains constant speed on the track. The academic definition of velocity is speed and the associated direction, a vector. A car traveling in a circle is constantly changing direction. However, most people, including physicists when they are not writing textbooks, treat velocity and speed as interchangable such that a car going a constant speed on a circular track would be considered to have a constant velocity even though the direction in which it is traveling is constantly changing.

The force of gravity is responsible for changing the in which a satellite moves?

The direction at which it moves. Since velocity is made up of a speed and a direction, you might also say that it changes the satellite's velocity.

Why is it that an object can accelerate while traveling at a constant speed but not at a constant velocity?

"Velocity" means a speed and the direction it's in. "Acceleration" means any change in velocity ... the speed, or the direction, or both. So ... -- If you keep going in the same direction but change your speed, then your velocity has changed, and that's called acceleration. -- If you keep going at the same speed but change your direction, then your velocity has changed, and that's called acceleration. -- If your speed changes and your direction also changes, then your velocity has changed, and that's called acceleration. -- If there's no acceleration, then you can only be moving at a constant speed in a straight line. That's the only kind of motion you can have without changing velocity.

What is formulas finding speed and velocity?

velocity = distance / time There are also some formulae involving acceleration; for example, in the case of constant acceleration: velocity = initial velocity + acceleration x time If the acceleration is not constant, an integral is used instead.

What is uniform circular motion?

Uniform circular motion describes motion in which an object moves with constant speed along a circular path.In physics, uniform circular motion describes the motion of a body traversing a circular path at constant speed. The distance of the body from the axis of rotation remains constant at all times. Though the body's speed is constant, its velocity is not constant: velocity, a vector quantity, depends on both the body's speed and its direction of travel. This changing velocity indicates the presence of an acceleration; this centripetal acceleration is of constant magnitude and directed at all times towards the axis of rotation. This acceleration is, in turn, produced by a centripetal force which is also constant in magnitude and directed towards the axis of rotation.
