Gravity affects every object differently but when dropped at the same height and time, they will hit the ground at the same time .
Why acceleration is the same.Force, mass and acceleration are related by f = ma, otherwise written a = f/m.
The gravitional force exerted by the earth is proportional to the mass of the falling object. If f=gm and a=f/m, then the acceleration equals gm/fm. This means that acceleration equals g whatever the mass of the object.
Exactly correct.
Like a breath of fresh air !
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.
True

Yes, that's correct.

Air resistance decreases acceleration of falling objects
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.
To acceleration (change in velocity).
This is known as terminal velocity.
On earth, the mass of an object has no effect whatsoever on its acceleration due to the force of gravity. All objects fall with the same acceleration, regardless of their mass. Any observed difference is due entirely to air resistance.
It's true, it's true! Galileo proved it.
Air resistance causes friction and slows an object.
The difference is due to inertia. Inertia is the resistance to a change in motion (acceleration). A more massive object will have greater inertia, and therefore a greater resistance to a change in motion, resulting in a slower acceleration. A less massive object has lower inertia, and therefore less of a resistance to a change in motion, resulting in a faster acceleration.
