The amount of horizontal force needed to keep a box sliding along a horizontal floor is equal to the product of the coefficient of kinetic friction between the box and the floor and the normal force pushing up on the box from the floor, which is equal to the weight of the box. As long as the characteristics of the box and the floor remain the same (neither is polished, lubricated, etc.), the coefficient of kinetic friction remains constant. Therefore, the horizontal force needed to keep the box moving across the floor is directly proportional to the weight of the box.
The empty cardboard box exerts more pressure on the ground because its weight is distributed over a smaller surface area compared to the same piece of cardboard that has been flattened. When flattened, the weight of the cardboard is spread out over a larger area, resulting in less pressure.
An empty cardboard box can float because of its shape and the material it is made of—cardboard is lightweight and has air pockets that provide buoyancy. When placed in water, the box displaces water equal to its weight, allowing it to float.
It is easier to squeeze an empty bottle because there is less resistance from the air inside the bottle compared to the water. The water in a full bottle creates more pressure and resistance when you try to squeeze it.
NO
No. The cardboard in milk cartons contain plastic, and your disposal won't enjoy the cardboard.
It will float until the cardboard becomes saturated and eventually sinks.
Empty space is a vacuum.
The empty cardboard box exerts more pressure on the ground because its weight is concentrated on the bottom. When the cardboard is flattened for recycling, its weight is distributed over a larger area, reducing the pressure exerted on the ground.
It is easier to push a toy chest along the floor when it is empty because the weight is significantly reduced, resulting in less friction between the chest and the floor. The force required to overcome this friction is lower when the chest is lighter. Additionally, an empty chest has less inertia, making it easier to initiate and maintain motion compared to a full one, which is heavier and more cumbersome.
Use a cardboard box! Save the Earth! RECYCLE! ?
An empty box has less mass and therefore requires less force to move it. On the other hand, a box full of books has more mass, making it heavier and harder to push because it requires more force to overcome inertia.
When I was raising German cockroaches for insecticide resistance in the Navy, I used cardboard. The little ones like to hide and the corrugated parts of the cardboard were perfect for that. So, yes, I guess it is attractive as a harborage. The less you have the better.
