An object has a constant velocity when it is not being acted upon by a force (or an unbalanced force) (zero is still a velocity).
It is essentially impossible to have a pure constant velocity on earth because of gravity, friction, air resistance, and the rotation of the planet, the orbit of the planet around the sun, and the orbit of the sun around the Milky Way. However, in a single reference plane (the surface of the earth), one may be able to approach it as long as forces are balanced.
Even in space, there are forces of gravity and rotational momentum that must be considered.

Can an object traveling at constant velocity have acceleration?
No. An object traveling at a constant velocity is not accelerating.
Can an object be accelerating if it has constant velocity?
No. The definition of acceleration is the change in an object's velocity over time. Acceleration must then be zero since velocity remains constant.
Is the velocity of an object in UCM constant?
no
Is the velocity constant for an object in uniform circular and why?
The velocity of an object in uniform circular motion is constant, because, velocity is the rate of change of position at a given time or speed.
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 an object traveling at constant velocity have acceleration?
No. An object traveling at a constant velocity is not accelerating.
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.
What happens to the velocity of an object even if the speed of an object remains constant?
Velocity can change even if speed is constant.
What are diifferent word for object?
a "body" "moving body" an "object" is moving with constant velocity. [OR] a "body" is moving with constant velocity.
If an object moves with constant acceleration what happens to the velocity?
The velocity increases at a constant rate.
Can an object be accelerating if it has constant velocity?
No. The definition of acceleration is the change in an object's velocity over time. Acceleration must then be zero since velocity remains constant.
Is the velocity of an object in UCM constant?
no
Can an object have zero velocity and nonzero acceleration?
Yes. An object moving at constant velocity has zero acceleration. The constant velocity van be any constant including zero velocity. Mathematics acceleration a=dv/dt = 0. Solving this gives v = constant.
Is the velocity constant for an object in uniform circular and why?
The velocity of an object in uniform circular motion is constant, because, velocity is the rate of change of position at a given time or speed.
What are the conditions of an object to stay at rest to keep on moving at constant velocity or to move with increasing velocity?
If the sum of all forces on an object is zero, then the object remains in constant velocity. Constant velocity means motion in a straight line at a constant speed. "Rest" is just constant velocity with a speed of zero. If the sum of all forces on an object is NOT zero, then the object's velocity must change. The change may consist of speeding up, slowing down, or turning in a different direction. If the sum of the forces is in the same direction as the object's motion, then the object must speed up.
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.
What is velocity if the net force is 0?
If the net force on an object is zero, then velocity of the object is constant ... it moves in a straight line at a constant speed.
