Because here on Earth, in the 'laboratory' where you must make all of your observations,
everything you see falling must fall through air. The presence of air has a substantial
effect on what you observe.
If you could do the experiments without air, and have nothing but gravity affect your
falling objects, you would see a feather and a truck fall with the same acceleration,
reach the bottom at the same time, and hit the ground with the same speed.
because of the differences in air resistance.
Yes. Gravity always works.
The forces of gravity always pull two objects toward each other.
Objects will always be pulled to the center of the mass.
yes
Only until they hit the ground or the floor.
because of the differences in air resistance.
gravity will always be the same it is always stronger than objects but it will never change.

The velocity in the x direction would be constant because gravity only affects the vertical components of objects. The velocity in the y direction would increase due to the constant acceleration due to gravity. The acceleration due to gravity on Earth is always -9.81 m/s^2.
Yes. Gravity always works.
Gravity. The object starts at zero velocity, and gravity always pulls the same. Drag, however, increases when velocity increases. Terminal velocity is when gravity has accelerated the object to the speed where drag is the same as gravity.
The forces of gravity always pull two objects toward each other.
Objects will always be pulled to the center of the mass.
