gravity
Gravity is a force that accelerates the falling object towards the ground.
Gravity is forcing an object to fall to the ground. Another force is friction from air pressure on the falling object.
Because of force
Not a question.
Nothing is opposing an object falling to earth. Gravity is causing an object to fall back to earth which is opposing the object from leaving earht. If anything the force that opposes gravity is the force at which an object is projected.
It's terminal velocity. This depends primarily on the object's cross section, its aerodynamic coefficient, and the density of the air it's falling through.

When THE FRICTION BETWEEN THE OBJECT AND THE ATMOSPHEREequals the force of gravity on a falling object the object reaches terminal velocity.

Because of force
That all depends on the strength and direction of the force. If the object is already "falling", then there must already be the force of gravity acting on it. The effect of any other force will depend on how the strength and direction of the other force relates to the strength and direction of the gravitational force. -- If the new force is directed up, it will slow the falling object, and possibly even make it stop falling and start rising. -- If the new force is directed down, it will make the falling object fall faster. -- If the new force is horizontal, it will make the object move horizontally as well as continuing to fall. -- If the new force is horizontal and strong enough, it will place the falling object into Earth orbit.
