That would be the escape velocity of Earth, about 11.2 km/sec. I am assuming that the object falls from far, far away, and that air resistance is negligible.

Will the object accelerate in free fall because the only force acting on its gravity?
A falling object will continue to accelerate when free falling, but each object has a maximum speed which it can reach (but go no faster than this speed) when free falling from great heights. True.
When a object falls what does it reach because of air resistance?
When an object falls, air resistance causes it to reach a terminal velocity. After that, it does not increase the speed of falling, no matter how far it has still to fall.
An object launched from Earth must attain a speed of 7900 m per second to achieve a low orbit What happens if the object its maximum speed is less than 7900m per second?
If the object has less speed, then it will fall back to Earth.
What happens if the object its speed is less than 7900 ms but must attain a speed of 7900 ms to achieve low orbit. What happens if the object its maximum speed is less than 7900m per second?
Then it will fall back to the Earth.
Does an objects acceleration increase while in free fall?
No, it will decrease in magnitude until the wind drag force is equal to the object's weight. Therefore it will reach a maximum velocity (speed) that it will maintain until it hits something.When in free fall, ALL objects have the SAMEacceleration of ~9.8 m/s2. This means that for every second that passes, the velocity of an object in free fall will increase 9.8 m/s more. This is when neglecting drag force from air which at the beginning ofthe fall is small.As the object increases its velocity, drag force becomes important and will increasewith the objects velocity until is equal to the object's weight. During this time theacceleration of the object is reduced in magnitude down to zero (when drag forceis equal to the object's weight) and the velocity has reached a maximum that staysnow constant.

What is maximum velocity?
maximum velocity is the highest possibly speed an object can travel before the forces acting on it reach an equilibrium and it is no longer able to accelerate. For example a parachutist will fall and accelerate rapidly until the air resistance pushing upwards against her downward force becomes balanced and her speed is steady, its more commonly known as 'terminal velocity' not maximum.

What happens to the distance you fall during each second?
If you fall from a very considerable height then initially the distance that you fall will increase with each second that you fall. However, air resistance increases markedly with speed and this causes your acceleration to decrease so that you reach a maximum speed (terminal velocity)
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.
Does different speed of two objects effect the time it takes to reach the ground?
If thrown horizontal from same height the faster object will travel farther horizontally, but time to fall is the same. If thrown straight up, the faster object will take longer to fall

What you should do if you are driving to the maximum speed limit when sleet starts to fall?
You always adjust your speed to road conditions. Or you maintain the maximum speed for a short time and then get buried ;).
Why falling objects don not move forward with a speed of 17700 mph?
And what makes you think an object would fall, or should fall, precisely at such a speed? How do you get that number? - Anyway, that's not the way our Universe works. Without air resistance, an object that falls downward falls faster and faster - its speed increasing by 9.8 meter/second every second. With air resistance, a falling object will eventually reach a speed at which friction (air resistance) balances the downward force of gravity. This speed is different for different objects.
Do all objects not aided by the air fall to the ground at the same speed?
Yes all objects fall at the same speed but there are objects that are aided by the air that don't fall to the ground at the same speed. For example, a feather and a brick. A feather is a object that is aided by air. A brick is a object that wind cannot blow away. If I drop both of them down with the same time down a 100 feet building, then definitely the brick will totally reach the ground first ............ well and it will get crushed into pieces while the feather might be blown away into a different place and reach the ground last.:) :):):):):):):):):)
