In the frame of reference in which the object is stationary, its speed is zero.
(Actually, that's kind of a definition of "stationary".)
Stationary object refers to an object that is not moving
If acceleration means to increase in speed or pace, then a stationary object is static, without movement, without acceleration. But, if an object is moving at a constant rate, then I suggest acceleration is not present, unless, or until the objects speed increases. Yes, an object with no acceleration may be stationary.
If the curve is horizontal, then the speed is constant. If that horizontal graph lies on the x-axis, then the constant speed is zero, and the object is stationary.
-- acceleration = 0 -- velocity (speed and direction) exactly equal to the observer's velocity
The forces acting on a stationary object are:PushPullGravity
WHAT THE SPEED OF STATIONARY OBJECT?
Nothing

Not accelerating. It could be stationary or moving at a constant speed.
"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.
0 velocity 0 acceleration The forces on the object are balanced: it is in equilibrium. (The forces are balanced on any object with 0 acceleration, even if it is moving.)
When its position changes with respect to a point of reference.
Object will change distance time graph when speed is changing. Distance time graph don't changed indicate of the stationary.
