v.Does high fluid velocity and low fluid velocity affect the value of Cd?
Yes
When an object is released in a fluid is the drag force less than its weight before it reaches terminal velocity?
When an object is released in a fluid is the drag force less than its weight before it reaches terminal velocity?
Do bubbles reach terminal velocity?
It depends on the type of bubbles. Hydrogen bubbles are often used to visualize aerodynamic flows around models. How you would work out their terminal velocity is by balancing their drag force and buoyancy force. First you would need an estimate of the bubble diameter, somewhere around .025 mm. For water, density of fluid =998 kg/m3 and fluid viscosity = 1.12*10-3 Pa*s FB=density of fluid*volume of bubble*gravity FD=3*pi*fluid viscosity*diameter*velocity of water At the terminal velocity FD=FB, you should have all the other variables, just rearrange to solve for the terminal velocity.
What are the factors that affect fluid friction?

How would changing velocity affect acceleraition?
the more viscus the fluid, that faster is moves
How does concentration of a fluid affect the motion of falling objects?
The higher the concentration of a fluid, the longer the time it takes for an object to fall and therefore the smaller the terminal velocity.

What are the factors that affect viscosity?
Temperature, concentration, sometimes also internal fluid velocity. Moreover density, type of liquid, surface where it flows, viscous drag.

Does the velocity of freely falling body remain uniform?
If you mean in atmosphere, the answer is "yes". It's called "terminal velocity." What the velocity is depends upon the shape of the object, because of the resistance of the atmosphere. Mind you, not the weight, since all objects are accelerated at the same rate in gravity. But if you're a great wide object, your terminal velocity (the fastest you can go) will be lower than if you're a ball bearing. In the absence of atmosphere, the answer is "no," because you will accelerate (non-uniform velocity) until you don't anymore.
What affects air resistance?
Fluid density, relative velocity, and object shape affect air resistance.
What is a velocity potential?
A velocity potential is a scalar function whose gradient is equal to the velocity of the fluid at that point. If a fluid is incompressible and has zero viscosity (an ideal fluid) its velocity as a function of position can always be described by a velocity potential. For a real fluid this is not generally possible.
How fast Does it take to reach maximum speed in a free fall?
Terminal velocity is dictated by the gravitational attraction between the bodies, intermediary fluid properties, and drag coefficient.
What factors affect water potential?
solute concentration and pressure
