When the force of friction due to air resistance at that speed becomes
equal to the object's weight. At that point, the sum of the vertical forces
on the object is zero, so it no longer accelerates.
When the downward force on it as a result of gravity is matched
by the upward force on it as a result of air resistance.
At a certain speed, the downward pull of gravity will be compensated by the upward force of air resistance - so the object will no longer accelerate.
Its the air resistance that causes the free falling body to reach its terminal velocity
Absolutely correct.
The velocity of a dropped and falling object goes on increasing due to acceleration due to gravity. It is given as v = gt So as t increases then velocity v also increases. Value of g is 9.8 m/s2
Earth's gravity
Yes. - And please don't combine "does" and "is" in the same question that way.
Its the air resistance that causes the free falling body to reach its terminal velocity
Absolutely correct.
The fastest velocity a falling object can reach is called its terminal velocity. This happens when the force of air resistance is equal to the downwards force of weight (gravity), so the object is in equilibrium, and thus reaches a constant velocity.

Objects in freefall only accelerate at 9.8m/s2 if air resistance is ignored. Because friction will gradually cause a falling object to reach terminal velocity, most objects won't accelerate at exactly 9.8m/s2.

As objects fall, they are accelerated by the force of gravity, which causes them to continually fall faster, until they either reach the ground, or until they reach what is known as terminal velocity, which is the speed at which air resistance is equal to the force of gravity, so that the falling object does not accelerate any more.
all objects have a terminal velocity once youu reach terminal velocity you can not fall any faster
There is no drag in a vacuum to act against the acceleration.
The Answer Is Roughly 7 Miles Per Second
We will reach terminal velocity just before we hit the ground, then the result of our velocity will be terminal.
