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

Can an object have constant velocity and still have varying speed..explain?

Velocity is a vector. A vector has a magnitude and a direction. The scalar or magnitude portion of velocity is speed. Velocity is a constant only when both the speed and direction are not varying. Hence, when the speed is changing, the velocity cannot be a constant.


Is it possible to have an constant acceleration and variable velocity?

Yes, the velocity of a constantly (or not constantly) accelerated object will vary. Velocity is distance per unit time with a vector. It's speed (distance per unit of time) in a given direction. Under constant acceleration, the velocity is changing at a constant rate. But the velocity is changing. It is varying. The object could be speeding up or it could be slowing down. Or it could be changing direction. Any of these change velocity. An object that is experiencing constant acceleration will have its velocity varying. Why wouldn't it have?


If the instantaneous velocity of an object remains constand can its instantaneous speed change?

No. Speed can remain constant when velocity changes, but velocity can't remain constant when speed changes.


Can an object be moving at a constant speed and acceleration?

When the acceleration is at constant 0, then the velocity will be constant.


Under what conditions is the magnitude of average velocity of an object equal to its average speed?

The magnitude of average velocity of an object equal to its average speed if that object is moving with CONSTANT velocity.

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.

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.


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

Yes. In order for an object's velocity to be constant, its speed and direction of motion must both be constant. An object moving in a circle, for example, has varying velocity, even if its speed is constant. This situation is known as "uniform circular motion," and the acceleration in this case is called "centripetal [center-seeking] acceleration."


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

Yes, for example, if it moves in a circle.


Can a body have a constant velocity but varying speed?

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


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 varying speed if its velocity constantif yes?

No, because constant velocity means constant speed and constant direction


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 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.
