Gravity.
The motion of a picture hanging from a nail doesn't change because the force of gravity acts only in the vertical downward direction, which does not affect the horizontal motion of the picture. As long as there are no external forces acting on the picture, it will remain stationary in the horizontal direction.
The main forces acting on a framed picture on a shelf are the force of gravity pulling it downward and the normal force exerted by the shelf pushing it upward. Additionally, there may be frictional forces between the picture and the shelf that can prevent it from sliding or falling off.
A mass is hanging from a spring experiences the force of gravity.
Two forces acting on a hanging object are tension, which is the force exerted by the string or rope holding the object up, and gravity, which is the force pulling the object downward towards the Earth.
When a mass is hanging from a spring, the forces acting on the mass are the force of gravity pulling the mass downward, and the spring force pulling the mass upward. When the mass is in equilibrium, these two forces are equal in magnitude but in opposite directions.

When a pen is hanging, two forces act on it - the upthrust and the force of tension in the string.
The law that explains why a picture hanging on a wall does not move is Newton's First Law of Motion, also known as the law of inertia. This law states that an object at rest will remain at rest unless acted upon by an external force. Since the picture is supported by a hook or nail and there are no significant external forces acting on it, it remains stationary. Thus, the picture stays in place unless something causes it to move.

Gravity is a force
The main forces acting on a framed picture on a shelf are the force of gravity pulling it downward and the normal force exerted by the shelf pushing it upward. Additionally, there may be frictional forces between the picture and the shelf that can prevent it from sliding or falling off.

When a pen is hanging, the main forces acting on it are gravity pulling it downward and tension in the string supporting it. Gravity creates a downward force on the pen, while the tension in the string provides an upward force to keep the pen suspended.
Balanced forces do not change its motion (no acceleration). Unbalanced forces changes the motion of the object (acceleration).
