A force can move a stationary object.If force is applied to a stationary object, does it always move?
Answers
It depends on the sum of all the forces on the object. Applying one force doesn’t tell you about the motion of the object unless you know what other forces (due to such things as gravity, friction, glue, nails) are doing.
OR
a stationary object only moves under a resultant force. And if the forces applied can generate a resultant force, then yes, the object always moves.
however when you are talking about pushing a box against the ground, it doesn’t move because the ground provides normal contact force which is equal and opposite to pushing force hence the resultant force is 0.
When talking about objects movements, we are more interested in the resultant force rather than all forces applied.

Stationary objects have forces on them.
All objects undergo some squashing or stretching when a force is applied to them.
When an object pushes on another object the first object squashes the second object which pushes back
