What is a force that acts in an upward direction that opposes the downward force of an object?

The force that opposes a downward force on an object would be called the "normal force". For example, it is as a result of the normal force that people do not fall though the ground the same way that they fall through the air.

If the air moves faster above an object does pressure push the object upward or downward?
upward
If the air moves faster below an object does pressure push the object upward or downward?
upward
An object is dropped and falls to the ground with acceleration of g if its thrown upward at an angle its acceleration would be 0 larger than g g upward g downward or none of the above?
9.8 meters per seconds squared in the downward direction.
What fluid opposes lift?
Compressible fluid force opposes lift. Lift is the upward force due to the fluid flow around an airplane wing. Weight is a downward force caused by gravity which opposes lift.
Is it possible for an object with constant negative acceleration to change the direction in which it is moving?
Sure. Anything you toss with your hand has constant acceleration after you toss it ... the acceleration of gravity, directed downward. If you toss it upward, it starts out with upward velocity, which reverses and eventually becomes downward velocity.
When the upward and downward forces on a falling object or changes its direction is called an?
Terminal Velocity.
A movie is made showing successive frames for an object accelerating downward. If the sequence is run backward would the object accelerate upward or downward?
UPWARD UPWARD UPWARD

When acceleration upward or downward direction is taken positivw or negative?
If it is gravitational acceleration then it it is positive in downward and negative in upward direction..if it is not gravitational acceleration then it is depending upon the value of acceleration.
What are the force acting on a fallen object what direction are these forces?
Assuming you mean "falling": the main forces are gravity (downward), and friction (in the direction opposite to the object's movement - for example, if the objects falls straight down, that would be upward).

Can something move 1 direction and have net force in the other direction?
Yes. What the net force does is affect acceleration. For example, when you throw an object up, once it is in the air the net force on it is downward - so of course it accelerates downward. But due to the fact that it was initially moving upward, it will continue moving upward - at least for a while.
Why does a projectile move upwards when thrown upwards even though a force of gravity acts downwards on it?
In the act of "throwing", the thrower imparts an upward velocity to the object, by temporarily applying an upward force to it that's greater than the downward force of gravity. During that brief period, the sum of the forces on the object is directed upward, so it accelerates in that direction. After the throwing ends, however, the only force on the object is the force of gravity, directed downward, so its acceleration is downward. That means that the upward velocity becomes smaller and smaller, until it's zero at the peak of the arc, and the velocity then becomes downward as the object begins to fall from its peak..
