It it possible for an object to be sationary while under acceleration?

"Stationary" means zero speed. The object's speed is not changing, and the direction of the speed is obviously also not changing.
By definition then, acceleration is zero.

What does the area under an acceleration time graph show?
The area under an acceleration-time graph is equal to the object's velocity (not change in velocity).
The free fall acceleration of an object under earth's gravity is directed where?
The center of the Earth.
Is it possible for an object in freefall to have no acceleration?
No, but it is possible to not have an increase in speed. Because velocity is a directional quantity, not a scalar one, an object in freefall (by definition within a gravity field) is always under acceleration, just not necessarily one that alters its speed or even its position. Objects in orbit around a planet are in freefall (hence weightlessness) where the tangential component of their forward motion opposes the pull of gravity.
What is the distance an object travels each second for objects falling under constant acceleration?
2.
Does pressure on an object affect its acceleration?
A submarine deep in the ocean is under great pressure, and a space capsule outside the atmosphere is under zero pressure. Both of them are capable of high acceleration, zero acceleration, and anything in between. The pressure is irrelevant.
How does acceleration change when object is thrown veritcally upward under ideal conditions?
From the time the object leaves your hand, its acceleration doesn't change at all ... it remains constant at 9.8 meters (32.2 feet) per second2 downward. Well, we have to admit that the acceleration does change to zero once the object hits the ground.
Is it possible for an object's weight to be different than its mass?
More then possible! It is so by definition. Mass is the "amount" of material in an object; weight is the force the object exerts under the influence of gravity.
Under what circumstances can an object moving with an constant speed (uniform magnitude oits velocity) have an acceleration?
When the direction changes. A simple case is an object moving in a circle, at constant speed.
What is The acceleration of a falling object under the influence of earths gravitational force?
If no other forces (such as friction) act on an object, or if friction is insignificant (such as, when a heavy object just begins to fall), the acceleration is 9.8 meters per second square. This means that every second, the speed will increase by 9.8 meters per second.
When will you say a body is in uniform acceleration and non-acceleration?
"Uniform acceleration" means that acceleration doesn't change over time - usually for a fairly short time that you are considering. This is the case, for example, when an object drops under Earth's gravity - and air resistance is insignificant. "Non-uniform acceleration", of course, means that acceleration does change over time.
If you put a force of 10 n on an object and the object has the mass of 5 kg what will the acceleration of that object be?
If operating in free space, the speed of the object will be constant. If not operating in free space, but under the effects of gravity, then apply gravitational formulas to find the answer.
When an object is traveling in a circular path around another object?
Yes an object can be accelerate if its moving along a curve path because when the object moves along a curve path it has constant speed and there is still change in velocity and change in velocity has acceleration
