A falling object will continue to accelerate when free falling, but each object has a maximum speed which it can reach (but go no faster than this speed) when free falling from great heights.
True.
The force of gravity pulls it down to the earth.
In that case, the object is said to be in "free fall". If the gravity is due to the attraction from a single object, such as Earth, the other object will accelerate towards Earth or whatever.
An object will accelerate if and only if there is a net force acting on the object.
weight, The weight of an object is the force of gravity acting on it.
Gravity must be the only force acting on the object, to produce downwards vertical acceleration. There is no force acting in the horizontal direction because there is no acceleration.

An object will accelerate in the direction of the net force acting on that object.

Its weight causes it to accelerate. That is in simple terms. When an object falls to the ground, it still has mass, it still has weight, and it has constant forces acting upon it, such as gravity.
If there is no air resistance, gravity will accelerate the falling object, that is, it will change its velocity.
If the object doesn't accelerate, then the forces are balanced - meaning that the vector sum of forces is equal to zero. If the object does accelerate, then the forces are unbalanced - the sum of all forces is not equal to zero.What the force are really varies from case to case. In general, there usually is at least the gravitational force acting on an object, and if the object doesn't accelerate, that means there must be at least one other force acting on the object. Here are two examples:A book resting on a horizontal table. Gravity pulls it down. The table pushes the book up.Some object resting on an inclined surface. In this case, the forces to counteract gravity are a combination of gravity and friction forces.
The object will accelerate.
Earth's gravity pulls all objects toward its center of mass, or in most cases toward the surface. Gravity is a property of matter,and causes every mass to exert a force on every other mass. In this case, the Earth's gravity applies a force to every object on it, and that force will accelerate an object toward the Earth's center, unless it is prevented by some intervening mass. It will still have the potential to accelerate again if the intervening mass is removed.
