# Is constant speed current velocity?

###### Wiki User

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.

### Can you go around a curve with constant velocity?

No. Constant velocity implies a constant speed, AND a constant direction.No. Constant velocity implies a constant speed, AND a constant direction.No. Constant velocity implies a constant speed, AND a constant direction.No. Constant velocity implies a constant speed, AND a constant direction.

### Can an object have constant velocity and but variable speed?

No. Velocity has two parts, speed and direction A constant velocity means that both the speed and the direction must be constant. So a constant velocity must have a constant speed.

### Can the speed of an object changes if there is constant velocity?

No, constant velocity implies constant speed. But velocity can change even when speed remains constant, since speed is a scalar quantity but velocity is a vector quantity.

### Is constant speed constant velocity?

No. Velocity includes a direction vector, which speed does not have.

### 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.

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

No. Speed is the magnitude of the velocity. If either or both the speed and direction vary, the velocity is not constant.

### 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 a particle with constant speed be accelerating what if it has constant velocity?

Velocity is speed together with its direction.Acceleration indicates a change in velocity ... speed or direction or both.Change of direction means acceleration, even if speed is constant.Constant velocity means constant speed and direction ... zero acceleration.

### Does constant speed mean constant velocity?

No. Circular motion can have constant speed but varying velocity. Constant speed means constant speed in any direction, like a car on cruise control turning a corner. Constant velocity means constant speed in a straight line. If the direction changes, that's considered a change in velocity.

### 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.

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

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".

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

No. Velocity is the combination of speed and direction. If it is constant, then both the speed and direction are constant. On the other hand, velocity can vary even is speed is constant, since the direction can change.

### What is the different between constant velocity and constant speed?

constant velocity is when you maintain speed and direction, this usually is in a straight line, and constant speed means that your speed is always constant at all times.

### 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 constant velocity but a varying speed?

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

### 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 a varying speed if its velocity constantif yes?

No, because constant velocity means constant speed and constant direction

### Does constant speed give you constant velocity?

No. The speed can be consant but direction can change and thus the velocity changes.

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

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

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

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

### What is nature of velocity in constant speed?

Velocity magnitude is unchanging at constant speed. The direction might change (velocity is a vector with both size (speed) and direction) if , for example, you are driving around a curve at a constant speed.

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

Yes. An object moving in a straight line at constant speed has constant velocity.

### Can object at constant speed can maintain constant velocity?

It can, but it won't always. In other words, if the speed is constant, the velocity may, or may not, be constant as well.
