A force applied to a stationary object can give the object acceleration, causing it to move.
Yes, the force of static friction between two stationary surfaces remains constant until the maximum static friction force is reached. It is equal to the force applied to the object up to a certain limit, at which point the object will start to move, transitioning from static to kinetic friction.
The force applied over a period of time to give a stationary object momentum is called impulse. Impulse is equal to the change in momentum of the object and can be calculated by multiplying the force applied by the time over which it is applied.
A balanced force refers to two equal and opposite forces that act on an object, resulting in no change in its motion. When balanced forces are applied, the object remains stationary or continues moving at a constant velocity.
Friction is a balanced force because it opposes the motion of an object in contact with a surface. As the object tries to move, friction acts in the opposite direction to prevent motion from occurring. When the force of friction equals the applied force, the object remains stationary, creating a state of balance.
A force applied to a stationary object can give the object acceleration, causing it to move.
"Motion" or "Momentum"
If an object is stationary on a surface then the forces acting on it are the Gravitational force and the Normal force(the force of the surface pushing back against the object). Technically you could be pulling(or pushing) that object from opposite directions with equal forces and it would remain stationary. The important thing to understand is that a stationary object remains stationary so long as the net forces applied to it equal zero.

Static friction. The frictional force is greater then the force applied, meaning the object can't move.
Friction is a balanced force because it opposes the motion of an object in contact with a surface. As the object tries to move, friction acts in the opposite direction to prevent motion from occurring. When the force of friction equals the applied force, the object remains stationary, creating a state of balance.
A stationary object does not move due to force acting upon it. For example, a book sitting on a table will remain stationary until a force is applied to it, such as someone picking it up or pushing it.
Static friction is the friction that prevents an object from moving when a force is applied. It occurs between stationary surfaces and must be overcome by an applied force in order for the object to start moving.
Force is what causes an object to start moving, stop moving, or change direction. The amount of force applied determines the object's acceleration and ultimately affects its motion. In summary, force is essentially responsible for any changes in an object's state of motion.
