The upward force is drag.
If the upward force acting on an object is greater than the downward force (its weight or force of gravity), the object will experience a net upward force causing it to accelerate in the upward direction. This could lead to the object moving upwards, overcoming the force of gravity pulling it downward.
If the object is moving upwards with a constant velocity, there is only one arrow in the diagram, and it points straight down, due to gravity. If it has a force pulling upward on it, there are two arrows, one up, due to the force, and one down, again, due to gravity.
An example of downward force of air against a moving object is drag. Drag is the resistance force exerted by air on an object moving through it in the opposite direction. It acts to slow down the object's motion by creating a counterforce against its movement.
The force that pushes against a moving object as it passes through water is called drag. Drag is caused by the resistance of the water pushing against the object as it moves through it. This force can slow down the object's motion.
On earth, the vertical acceleration of any object that's free to move vertically,and has no artificial force imposed on it, is 9.8 meters (32.2 feet) per second2,directed downward. The source of the acceleration is the mutual gravitationalattraction between the object and the earth.

If the object is moving at a constant speed, the net force on it is 0. So the upward force would have to be equal to the downward force (namely the weight of the object).

Friction. Opposing Force
The force that pushes against a moving object as it passes through water is called drag. Drag is caused by the resistance of the water pushing against the object as it moves through it. This force can slow down the object's motion.
On earth, the vertical acceleration of any object that's free to move vertically,and has no artificial force imposed on it, is 9.8 meters (32.2 feet) per second2,directed downward. The source of the acceleration is the mutual gravitationalattraction between the object and the earth.
The force that acts against the gravitational force in the upward direction is the normal force. The normal force is exerted by a surface in contact with an object and is perpendicular to that surface. It prevents the object from falling through the surface due to gravity and is equal in magnitude but opposite in direction to the gravitational force acting on the object.
The net force on the object is upward, so the object accelerates upward in the fluid.
Buoyancy is the upward force exerted by a fluid that opposes the weight of an object placed in the fluid. It acts against the force of gravity on the object, allowing objects to float or be suspended in a fluid.
