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.
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.
Newton's 1st Law of Motion states that an object will maintain its speed when there is no net force acting on it. The question refers to free space and constant velocity -- the net force has to be zero. =========================
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.
An object maintains a constant velocity when the net force acting upon that object is zero. Therefore, a force pushing against the object that exactly opposes the force(s) due to friction (in both magnitude and direction) will result in a net force of zero, and the object will maintain a constant speed.
If a velocity or speed is constant there isn't an acceleration. This is because the acceleration is the change in speed or velocity and if it's constant then there sn't a change.
Yes. An object moving in a straight line at constant speed has constant velocity.
Velocity can change even if speed is constant.
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.
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.

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.

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