While this sounds like a question that is specific to a certain situation, it sounds like you're talking about air resistance. It always opposes motion and (for small objects) is modeled as being proportional to the magnitude of velocity.
The velocity of object always changes with wanted or unwanted outer forces.
When velocity changes, it is referred to as acceleration. Acceleration is the rate at which the velocity of an object changes over time.
When velocity changes, the speed and/or direction of an object's motion is altered. This can result in acceleration or deceleration, depending on the direction of the change in velocity. If the velocity increases, the object is accelerating; if the velocity decreases, the object is decelerating.
Wanted and unwanted outer forces will always change the velocity of an object.
If an object starts to accelerate, it is called gaining speed or increasing its velocity. Acceleration is the rate at which an object's velocity changes over time.

Force changes the velocity of an object by acceleration, a=F/m.

A change in an objects velocity is called acceleration. Velocity is defined as an objects speed of travel AND its direction of travel. Acceleration can change only an objects speed, only its direction or both. If there is no acceleration acting on the object, then the velocity remains constant.
velocity. When an object changes direction, its velocity vector changes, even if the object's speed remains constant. This change in velocity can be caused by forces such as gravity or friction acting on the object.
An increase in the magnitude of velocity is called acceleration. It refers to the rate at which an object's velocity changes over time.
This is not always the case. But if an object moves in a circle, at constant speed, its velocity will change. Velocity is a vector - consisting of the magnitude (the speed), and a direction. So by definition, if the direction changes, the velocity changes - you have a different vector.
