A feather with no momentum maintains constant velocity. Momentum is defined as the quantity of motion of a moving body, measured as a product of its mass and velocity.
In physics, net force refers to the overall force acting on an object. A feather with no net force on it maintains constant velocity.
An object at a constant velocity (or motion) has a overall force of 0.
Zero.
Constant velocity has speed always constant along the direction with respect to time. Variable velocity changes its speed with respect to time. Constant velocity has zero acceleration. Variable velocity has non-zero acceleration . An object moving at a constant velocity maintains both the same speed and direction. An object moving at a variable velocity can be changing speed or direction of travel or both.
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.

Zero.
The answer is very simple. The words "constant velocity" are the definition of zero acceleration.
An object that moves with constant position will have constant velocity or acceleration. This is said to be moving in positive direction and maintains the position.
Constant velocity has speed always constant along the direction with respect to time. Variable velocity changes its speed with respect to time. Constant velocity has zero acceleration. Variable velocity has non-zero acceleration . An object moving at a constant velocity maintains both the same speed and direction. An object moving at a variable velocity can be changing speed or direction of travel or both.
The velocity of a wave which maintains consatnt phase at all successive positions during propogation is known as wave velocity or phase velocity. The velocity of a group of waves which maintains constant poditions during the propogation is known as group 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.
Acceleration is the time rate of change of velocity. If velocity is constant, then acceleration is zero. Note: "100 km per h for 10 seconds" is a constant speed, but not necessarily a constant velocity, since we're told nothing about the direction. If the car moves in a perfectly straight line during those 10 seconds, then its velocity is constant. If it makes a curve, then its velocity is not constant even though its speed is, and there is acceleration.
