What happens when a box is pushed across a rough floor?

The force of friction acts to resist the motion of two surfaces in contact and applies to both surfaces. For instance, when a group of children attempt to push a box with a smaller child on a rough floor, the box will remain stationary due to the frictional force opposing their pushing effort. This frictional force emerges between the contacting surfaces, counterbalancing the applied force and preventing the box from moving.
