Gravity
Assuming that there are no other forces on the object, the force that causes the acceleration of a falling object is the gravitational force (attractive force that exists between two masses). In problems, this assumption is usually used.However, in Force = mass*acceleration it is important to remember it is net acceleration and net force. Thus, for an object falling in real life the acceleration is caused by the gravitational force and a drag force which results from the object moving through the air. You have to take into account all the forces on the object.

F = M A Acceleration is directly proportional to force. When force applied to an object is reduced to one third, the object's acceleration is reduced to one third.
If you meant to say mass instead of weight, the acceleration of an object is inversely proportional to mass, because F=ma. However for falling objects where acceleration is equal to gravity, the weight is not a variable.
The second law states that the acceleration of an object is dependent upon two variables - the net force acting upon the object and the mass of the object. The acceleration of an object depends directly upon the net force acting upon the object, and inversely upon the mass of the object. As the force acting upon an object is increased, the acceleration of the object is increased. As the mass of an object is increased, the acceleration of the object is decreased. To put it as it is often put: Force equals mass times acceleration (F = ma): the net force on an object is equal to the mass of the object multiplied by its acceleration.

Acceleration is caused by gravity or an outside force on the object.
Gravity
Acceleration of a falling object is directly proportional tothe force of gravity in the object's location.
Acceleration. A free-falling object falls at constant force, and thereby at constant acceleration.
-- The rate of acceleration of an object on the moon is(the net force on the object)/(the object's mass) .-- If the object is falling, with nothing but the force of gravity acting on it, thenits acceleration is 1.623 m/s2 (compared to 9.807 on Earth).
the acceleration of gravity is 9.8 m/s
That means that the acceleration of an object is caused by the force of gravity acting on the object.
Only one thing can be acceleration; the changing velocity of any given object. That's what acceleration is. Acceleration is caused by a net force on the object.

Because the acceleration depends on the gravitational force on the object. But the gravitational force on the object depends on its mass ... More mass = more force. Objects with less mass have less force on them, and objects with more mass have more force on them, and the force on each object is exactly enough so that each object winds up falling with the same acceleration.
