because they are fat
Objects fall to the ground because of the force of gravity.
Absolutely! In fact, gravity is an acceleration associated with massive objects. If you drop your pen off of your desk, it will accelerate at 9.8 meters per second per second until it hits the ground.
When falling to the ground (or even just in the air), the acceleration of an object depends on the gravitational pull of the object it is falling towards. Here on earth, all things fall relative to the earth which causes an acceleration of 9.81 m/s^2
No, they fall at the same time.
In free fall an object regardless of its mass will accelerate at 9.8 meters/second/second or 32 feet/second/second assuming that you are on earth in a frictionless environment. This means that any two objects regardless of their mass will fall to the ground at the same rate.
In free fall, the force of gravity alone causes an object to accelerate in the downward direction.
Because in air there is gravity which can make that to accerelate

gravity is what makes objects fall
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.
Not in a vacuum. All objects, regardless or mass, density, or whatever, fall with the same speed in a vacuum. Some objects may appear to fall more slowly than others (example, a flat piece of paper or a feather vs. a rock), but this is usually due to air resistance. All objects, when falling on earth, accelerate towards the ground at a rate of 9.8 meters/seconds squared.
All objects accelerate if the forces acting on them are not balanced.
