How do you calculate upward force to keep an object in the air?

Basically, the upward force has to counteract the downward force of gravity. Thus,
the upward force has to be equal to the object's weight. There is not much
calculation to do here; just use the standard formula for weight:
weight = mass x gravity
Under normal Earth gravity, you can use 9.8 for gravity; thus, every kilogram has a
weight of about 9.8 newton, and therefore requires an upward force of 9.8 newtons
to keep it in balance.

What keeps a falling object from accelerating?
Assuming the object is in free fall the only thing that can keep the object from accelerating in the opposing force of kinetic friction upward by air (known as air resistance).
What force holds an object in a circular object?
Centripetal force is necessary to keep an object in a circular path.
Is it true that to keep an object moving a force must be apllied?
No, it is untrue. No force is required to keep a moving object moving.
Is a force to keep an object in motion?
No, a force changes an object's motion. F=ma= mdv/dt
What is the force that keep an object moving?
gravity

Is force always neede to keep an object moving?
Force is never needed to keep an object moving unless there is an opposite force trying to slow the object.
What force holds an object in a circular object?
Centripetal force is necessary to keep an object in a circular path.
Why do you have to exert extra force to get a heavy object moving and then have to keep applying force to keep it moving at constant velocity?
the heavier and the bigger the object the more force you need to use to keep it moving . the less weight and the smaller an object is the less force you need to use to keep it moving. it always depends on the weight of the object and the size of the object.
Is it true that to keep an object moving a force must be apllied?
No, it is untrue. No force is required to keep a moving object moving.
What is the force that keeps an object in motion?
An object which is moving doesn't need a force to keep it moving.
How can you keep an object the same if the force acting on the object were doubled?
The object will remain the same regardless of the amount of force you apply on it.
Is a force to keep an object in motion?
No, a force changes an object's motion. F=ma= mdv/dt
Is a force requierd to keep a object in motion?
No
What is the force that keep an object moving?
gravity
What force is needed to keep an object in circular motion?
Centripetal force
Why is less force neede needed to keep an object moving than to start the object in motion.?
The best, purest answer is: Because no force at all is required to keep a moving object moving.
