If there is no air resistance, gravity will accelerate the falling object, that is, it will change its velocity.
A falling object no longer accelerates, due to friction in the atmosphere, when the friction buildup equals gravity's acceleration. This is called it's terminal velocity.

air resistance
True
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 a falling object accelerates through air, its speed increases and air resistance increases. While gravity pulls the object down, we find that air resistance is trying to limit the object's speed. Air resistance reduces the acceleration of a falling object. It would accelerate faster if it was falling in a vacuum.
A: because earths gravity cannot be harnessed forever unless the earth is moving with you. B: because earths gravity is not strong enough to pull you along unless you are in space as friction from air resistance will stop you.
Air resistance creates friction and slows a falling object.

It reduces the acceleration of the falling object due to friction.

Air resistance causes friction and slows an object.

Air Resistance: a form of friction.
No. Terminal velocity is a particular kind of velocity and friction is a particular kind of force. The terminal velocity of a falling object is the maximum velocity it can have because air resistance prevents it from going any faster. And air resistance is a type of friction. So terminal velocity is due to a type of friction.
True
