Velocity can change even if speed is constant.

Yes. The velocity can change if the speed remains constant and the direction changes.
The velocity increases at a constant rate.
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.
If the object is moving at constant velocity, that's an indication that the net force on it is zero.
No. The definition of acceleration is the change in an object's velocity over time. Acceleration must then be zero since velocity remains constant.
No. Speed can remain constant when velocity changes, but velocity can't remain constant when speed changes.
Velocity is a vector quantity in which both magnitude and direction must be taken into consideration. For an object to have constant velocity, it is necessary that both the magnitude and the direction of the velocity must be constant. Even if either magnitude or direction is variable, velocity will not remain constant. On the other hand, speed remains constant if direction is changed and magnitude is kept constant, as speed is a scalar quantity.For an object to have constant velocity, it is necessary that the object move at a constant speed and not change course. That object must move in a straight line to have a constant velocity.
Displacement: Grows with time, at an increaing rate. Velocity: Grows with time, at a constant rate. Acceleration: Greater than zero, remains constant with time.
The velocity is constant and there is no net or unbalanced force.
The velocity can still change, even if the speed doesn't. This is because velocity is a vector - not only the magnitude is important, but also the direction.
An object with constant velocity has no acceleration.
Yes. Velocity is speed and direction so it can change velocity by changing direction.
The answer for the blank is "constant".
No. An object traveling at a constant velocity is not accelerating.
If the object is static (and remains static), or if it moves at a constant velocity, that means that the net force on the object is zero.
An object at rest has a constant velocity of zero. Both the object at rest and the object moving at constant velocity have zero acceleration.
When net force on an unconstrained object changes, the object's acceleration, velocity, position, and possibly speed and shape all change. Its mass remains constant.
Its magnitude increases steadily, at the rate of 9.8 meters per second every second.Its direction remains constant, pointing down.
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.
By balanced force, I assume Fnet is 0. By Newton's...2nd (?) law, when Fnet on an object is 0, velocity remains constant.
The definition of acceleration is: Any change of velocity, that is, speed or direction of motion. If an object is undergoing constant acceleration, then the definition says that its velocity must be changing.
Acceleration is the change of velocity per unit time. Once the object has a constant velocity, its acceleration will be zero.
Without force there is no acceleration and with no acceleration the velocity remains constant. When the constant velocity is zero the object is at rest.
If the sum of all forces on an object is zero, then the object remains in constant, uniform motion. 'Constant uniform motion' means motion in a straight line at a constant speed. The physical description of such motion is "constant velocity". "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.
