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 of
the fall is small.
As the object increases its velocity, drag force becomes important and will increase
with the objects velocity until is equal to the object's weight. During this time the
acceleration of the object is reduced in magnitude down to zero (when drag force
is equal to the object's weight) and the velocity has reached a maximum that stays
now constant.
false
In free fall in a vacuum, all objects fall at the same rate of acceleration. In air, however, friction comes into play, so that various objects can fall at different rates.
Yes. The acceleration depends on the aerodynamics of the shapes of the objects - not their mass.
False
Yes, exactly. Free fall results in constant acceleration.
yes, objects fall at a rate of 9.8m/swith acceleration. For every second in free fall you must add 9.8m/s to get the acceleration of an object.

Yes. The acceleration depends on the aerodynamics of the shapes of the objects - not their mass.
False
The acceleration is the same for all objects, as long as air resistance is insignificant. After a while, different objects will have different amount of air resistance. Also, even without air resistance, the speed depends not only on the acceleration, but also on how how long the objects are falling.
Constant acceleration
Yes, exactly. Free fall results in constant acceleration.
With the same acceleration.
objects c.g side
Yes, that is correct.
Yes. Neglecting the effects of air resistance, all objects near the surface of the earth fall with the same constant acceleration, regardless of their mass/weight.
