Buoyant force works against the force of pulling.
Any upward force works against gravity,since they act in opposite directions.
Friction.
Air resistance is not a downward force; it acts in the opposite direction of an object's travel. When a plane is in flight the forward force provided by the engines works against the backwards force of air resistance. If the engines are turned off the plane will begin to slow down. As a plane moves foreward the air moving over its wings creates an upward force called lift, which works against the pull of gravity.
because objects move when proper force is acted upon them which works on moving and changing these objects direction.

For an object moving through the liquid or gas that force is drag.
Buoyant force works against the force of pulling.
An object has a general tendency to keep moving - that's how our Universe works. No force is required to keep an object moving - unless there is another force that slows it down. Here on Earth, there are usually frictional forces that slow objects down, and therefore a force is required to counteract the frictional forces.

Gravitation, or gravity. It is the means by which objects with mass attract one another.
Friction.
This is the intermolecular force of hydrogen bonds.
