No. A body with constant velocity is either stationary or going at constant speed in a constant direction. The usual interpretation of speed and velocity goes like this.

A velocity is a vector with magnitude and direction. The magnitude is usually called its speed. Changing a speed must change the length of the vector and changing the length of the velocity vector has to change the velocity.

Can a body have a constant velocity but a varying speed?

No. Velocity is speed and direction. If you change either variable, the velocity will no longer be constant.

Can a body have a constant velocity but varying speed?

No. If the speed varies, the body accelerates, and velocity cannot be constant.

Can the speed of a body vary if its velocity is constant?

No. "Velocity" means the speed and direction of motion. If either of them is changing, then velocity isn't constant. (By the way, that's what "acceleration" means: Any change in velocity.)

Is it possible for a body to have acceleration when with constant velocity?

No. The definition of acceleration is a change in velocity, i.e. speed and/or direction. So constant velocity means zero acceleration.

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 a body have a varying speed if its velocity constantif yes?

No, because constant velocity means constant speed and constant direction

Can a body have constant velocity but changing speed?

No, not at all possible. But constant speed with changing velocity is possible.

Can the speed of a body be constant still varying its velocity?

Yes. Velocity is rate (or speed) in a given direction. If you change your direction but not your rate (or speed) then you have changed your velocity without changing speed.

Can a body have constant velocity but varying speed?

Yes, velocity involves speed and direction. So if the direction and the speed change at a certain rate, the velocity could stay the same.

Can a body have constant velocity and changing speed?

No, in order for the velocity to be constant, the speed has to be constant. Speed is a scalar, meaning that it is just a number. (A car goes 50 miles per hour). Velocity is a vector, which indicates that it needs a measure of its displacement and a direction. (A car is going 50 mph to the east). A body can have a constant speed but a changing velocity because the direction can change while the speed is constant. (A car goes 50 mph around a roundabout). However, a body can not have a constant velocity with a changing speed. A car can not be slowing down yet still be going the same speed and direction.

Can an objeact have constant speed and but variable velocity?

Speed is a scalar quantity while velocity is a vector quantity.It is possible that an object can have constant speed but if speed is constant while direction of motion is changing constantly then it means that body has variable velocity.An example of this phenomena is a body moving in a circle whose speed is constant but velocity is changing every instant due to change in direction at every instant.

Does a body moving with constant speed have constant velocity?

No. A body can have constant speed but changing direction thus changing velocity. For example, an orbiting body may have a constant speed s=wr, but its direction is constantly changing as it follows the curve of its orbit.

Why an object in a circular orbit at constant speed is it accelerating?

def " the rate of change of velocity is called acceleration" example. when we are driving ...after some time turn to enter in another street.. with the same speed....but the body have acceleration because there is change in velocity...as the velocity is vector quantity it depends on the magnitude as wall as direction...while on turning there is change in velocity so there is an acceleration is the body with constant speed.............

What is an example of an object that is accelerating but is traveling at a constant speed?

Acceleration is a change in velocity over time. Velocity has both speed and direction. A body moving in circular motion at constant speed is still accelerating because its direction is constantly changing. If either speed or direction changes, or if both change, the body is accelerating.

Can a body have a constant speed and a changing velocity?

"Velocity" means the speed of the object and the direction in which it's moving.If the direction changes, then the velocity has changed, even though the speedmay be constant.

Is it possible for a body to move in a circle with constant speed constant linear velocity?

No. The linear velocity can never be equal when speed is constant. This is because direction is changing and therefore linear velocity changes.

Is it possible for a body to have acceleration when moving with constant velocity explain?

the question is very simple.no a body does not have acceleration when it is moving with constant velocity ,because a body posses acceleration when its velocity is not remain conserved or constant.yes if a body have constant speed it may have acceleration but not in case of constant velocity.

Can a body have constant velocity but have variable speed explain?

No. Speed is the magnitude of velocity. If the speed varies, so will the velocity, even if you are moving in a uniform direction.

Is it possible that the velocity of a body changes and its acceleration remains constant?

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.

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

It is possible for a body to have acceleration when moving with costant velocity and constant speed?

constant velocity means no acceleration. An object can be moving at constant speed, like a satellite in orbit, but its velocity is changing because direction is changing

Can an object have constant speed but variable velocity?

I think a body in uniform circular motion can have a constant speed, but variable velocity. Since this body is in circular motion, it changes it's direction. Thus having a variable velocity.
