Newton's First Law of Motion states that an object remains at a constant velocity unless it has an unbalanced force acting upon it. That constant velocity includes zero, which means that a stationary object with no force applied to it will not move. Since velocity includes direction, then a moving object with no force applied to it will continue to move in a straight line at a constant speed.
That tendency is called inertia.
The tendency for an object in motion to remain in motion is called
It is called Inertia.

The change in velocity is just the change in velocity. The RATE of change of velocity - how quickly velocity changes - is usually called "acceleration".

It is called uniform motion because the object covers equal distances in equal intervals of time which is why it has a constant velocity.
No. A body with constant velocity is either stationary or going at constant speed in a constant direction. The usual interpretation of speed and velocity goes like this. A velocity is a vector with magnitude and direction. The magnitude is usually called its speed. Changing a speed must change the length of the vector and changing the length of the velocity vector has to change the velocity.
No. A body with constant velocity is either stationary or going at constant speed in a constant direction. The usual interpretation of speed and velocity goes like this. A velocity is a vector with magnitude and direction. The magnitude is usually called its speed. Changing a speed must change the length of the vector and changing the length of the velocity vector has to change the velocity.
Any skydiver can fall at a constant velocity. This is called the, "Terminal velocity". Since we do not have the picture that you mention, nothing more can be assumed.
Homeostasis
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.
newton's first law states: an object will remain at rest or at a constant velocity unless the forces on it become unbalanced. As the forces on the object are now balanced it falls at a constant velocity. For falling objects this is called the terminal velocity
It is called constant velocity. Rate is just another word for velocity. This, however, is dependant upon the path the object is taking. If it is moving in a parabolic path, or a curve of some sort (anything but a straight line), then the object is actually accelerating (as acceleration is a change in velocity OR direction.)
If the acceleration is constant, yes. However, the acceleration of an object can vary. The rate of change of acceleration is called jerk.
Not necessarily. Impulse Fdt=change in momentum which could be written as mdv (constant mass, velocity changing) or dmv (changing mass, constant velocity - the so-called conveyor belt problem. Imagine a hopper filled with (say) coal is feeding the coal on to a conveyor belt. The mass of the belt increases with time, so a force has to be applied to it to keep it moving at constant velocity.
when a body travels unequal displacement in equal interval of time or visa-versa, it is said to have non-uniform velocity
