# What is an example of constant speed with changing velocity?

###### Wiki User

Velocity is a vector, thus it has a direction. Therefore, you can change the velocity by changing direction. A great example of this is a ball on a string spinning at a constant speed, but it is continually changing direction, therefore, even though the speed is constant the velocity changes at every instant.

### What is an example of constant velocity with changing speed?

That isn't possible. You can have a constant speed and a changing velocity, but not the other way round.

### 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).

### Is it possible to have a changing velocity and a constant speed?

Yes it is possible to have a changing velocity at a constant speed. Velocity is defined as the rate of change of position therefore if the direction of the constant speed changes then that constitutes a changing velocity. For example driving in a circle means that the speed is constant but the direction changes as you drive :) Betlehem Semahge

### 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.

### Can a body have constant velocity but changing speed?

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

### Can an object have a constant speed and a varying velocity?

Yes. Velocity is a quantity that has both magnitude and direction. Speed is the magnitude of velocity. If speed is constant but the direction is changing, then the velocity is changing. An example is a car turning a corner without slowing down.

### If you are traveling around a curve at a constant speed of 30 km is the veiocity change?

Yes, the velocity is changing. Velocity is a quantity composed of the speed and the direction of motion. Constant velocity means: Constant speed, in a straight line. If the direction is changing, then the velocity is changing, even if the speed is constant.

### If a ferris wheel is rotating at constant speed is it moving at a constant velocity?

No. Velocity combines speed and the direction of motion.Constant velocity is constant speed in a straight line.In circular motion, the velocity is always changing even if the speed is constant,because the direction is always changing.

### Can you have constant speed but changing velocity?

Yes, certainly. You're fully entitled to it.Velocity is speed and its direction. If the direction of the motion changes,then the velocity has changed, even if the speed didn't.A fine example is a marble or a roulette ball zipping around a circular pathat a constant speed. The speed is not changing, but because its directionis constantly changing, so is its velocity.

### Why achanging velocity cannot maintaining constant speed?

A changing velocity can maintain constant speed if the motion is circular. The constant change in direction is a change in velocity, even if the speed is constant.

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

Of course, since velocity is a vector quantity and speed is a scalar quantity, velocity has something speed does not: direction. Thus, an object can travel at the same speed by has a changing direction of movement, and therefore a changing velocity. For instance, a ball on a string moving in a circle at the same speed is constantly changing its velocity, which results in its path of motion.Yes. Velocity is (speed and direction of motion). If direction changes, then velocitychanges, even if speed is constant.Examples:-- Car going around a curve at a constant speed has changing velocity.-- Anything traveling a circular path at a constant speed has changing velocity.

### 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.

### The car rounds the turn at a constant velocity of 90 mph?

If the car rounds the turn, then its velocity is not constant.Velocity is a thing that has magnitude and direction. The magnitude is what we call "speed".If the direction is changing, then the velocity is changing, even if the speed is constant.

### Can speed of a body change if its velocity is constant?

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.

### 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 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.

### A science book is being pushed across a table Can the book have a constant speed and a changing velocity?

It can have a constant speed, and a changing velocity, but it cannot have the two at the same time. Remember: Velocity = speed with a directional component.

### Why is a car traveling at a constant speed in a circle always accelerating?

Because its velocity is changing all the time. The speed is constant, the velocity is not.

### What is an Example of constant velocity?

constant velocity means the speed and direction are the same.

### Why the velocity of a race car going at a constant speed around an oval track is changing?

Because "velocity" consists of a speed and a direction. If the direction is changing, then the velocity is changing, even though the speed isn't. And here's another one for you: "Acceleration" means any change in velocity. So if the race car is going around an oval track at a constant speed, it's accelerating. ==&gt; Because its velocity is changing. ==&gt; Because its direction is changing. ==&gt; All at constant speed.

### Why is a car accelerating when it is circling at a constant speed?

The velocity is changing and is not constant. Velocity is speed as well as direction so there is a continuous change in velocity which means there is acceleration.

### What is the difference of constant speed and changing velocity?

Constant means that something doesn't change; "changing" means that it does. Speed is a magnitude - measured (for example) in meters per second. Velocity, on the other hand, is a vector - which means that the direction is also considered. If an object changes direction - for example, moving in a circle - it is possible to do so at a constant speed. However, since the direction changes, the velocity will - by definition - change.

### 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 constant speed current velocity?

No, it is not. Basically speed is a scalar whereas velocity is a vector.A car going round a circular track at constant speed has a velocity which is changing at every moment.
