compression is the internal force acting on the mattress as it is compacting/squeezing the particles of the mattress
When you sleep on a mattress, your body weight exerts a downward force on the mattress due to gravity. The mattress exerts an equal and opposite upward force on your body, providing support and keeping you from falling. These forces are internal to the system of you and the mattress.
Acting forces refer to the forces that are currently affecting an object or system. These forces can be external, such as gravity or friction, or internal, like tension or compression within a structure. Understanding acting forces is important in analyzing the motion and stability of objects.
The weight of the ruler is not included as a force acting on the system because it is an internal force within the system. Internal forces do not affect the overall motion of the system and therefore do not need to be considered when analyzing external forces acting on the system.
External forces act on an object from outside its system, while internal forces arise from interactions within the system itself. External forces can change the state of motion of an object, while internal forces contribute to the object's stability, structure, and internal interactions. The overall behavior of an object is determined by the net effect of both external and internal forces acting upon it.
The main forces acting on a free-standing structure are gravity, which pulls the structure downward, and wind or other lateral forces, which can push the structure from the sides. The structure itself also exerts internal forces to resist deformation and maintain its shape. Additionally, if the structure is on a slope, there may be forces due to the slope acting on the structure.

The forces acting on a stationary boat in still water are gravity acting downwards, buoyancy acting upwards, and drag acting to oppose any external forces like wind or current. These forces are balanced when the boat is stationary.
Balanced forces acting on an object do not change the object's position.
