Constant velocity is, well, constant. To measure it, measure the displacement through a given or fixed period of time. You'll have distance and time. Distance per unit time is speed. Distance per unit time (speed) with a direction vector is velocity. Velocity is speed in a given direction. If something is moving at constant velocity, it is moving at a constant speed in one direction. No changes in speed (no positive or negative acceleration, or, said another way, no acceleration at all), and no change in direction or heading.

What does constant velocity or acceleration mean?
"Constant" means that regardless of when you measure it, the result is always the same. "Velocity" means speed and its direction. "Acceleration" means the rate at which speed is changing, and the direction in which it's changing.
What is the velocity in which the body covers equal displacements in equal intervals of ttime?
In that case, the velocity is said to be constant.
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 you go around a curve with constant velocity?
Yes, it is. Trajectory also depends of direction of acceleration, not only it's magnitude. When you consider circular orbit, the agnitude of centripetal acceleration is constant, but the vector directions changes every moment to point constantly at the center.
Why areal velocity is constant in central force?
If the force is constant then this will make the velocity of the object spinning constant as well, and for the velocity to be constant all the forces must be balanced and therefore constant
Can constant velocity be zero?
Yes. Zero velocity is a velocity; if it is always zero then it is a constant velocity.

What is your acceleration if you have a constant velocity?
If your velocity is constant, then your acceleration is zero.

What is constant acceleration?
constant acceleration is a measure of a continuing increase in velocity per unit of time. another way to express it is: d²x/dt² = c where c is a constant
If you have a constant velocity do you have to have a constant speed?
Yes, speed is the scalar of velocity.
Why areal velocity is constant in central force?
If the force is constant then this will make the velocity of the object spinning constant as well, and for the velocity to be constant all the forces must be balanced and therefore constant
What is constant velocity in terms of physics?
Constant velocity means constant speed in a straight line.
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.
How can you determine the speed of an object that has constant motion if you have a distance vs time graph of the motion?
If constant motion means constant velocity then, total distance / total time = avg velocity => avg speed constant velocity => avg velocity = velocity
