1. It is easier to push a heavy object on a polished wooden because then the box will be easier to push across the floor.
kinetic friction
The carpet provides more friction
How rough it is and how heavy it is.
The friction between two stationary forces is called static friction. It is the friction that resists two objects to start moving against each other. Once in motion, the friction between two forces is called dynamic friction. Static friction tends to be greater than dynamic friction, which is why it takes more force to get a heavy box moving along the ground compared to keep it going.

Examples of SLIDING FRICTION is pushing a heavy rock in your path, or moving a box on the floor.
Sliding
friction releases thermal energy and releases speed and efficiency.
without friction, there wouldn't really be any inertia. according to wikipedia, "Inertia is the resistance of any physical object to a change in its state of motion or rest." For example, if you were trying to push a heavy box across the floor, the friction from the floor would prevent you from pushing it easily, and its inertia would also prevent it from moving. Basically, the friction is making it stick to the floor and not be able to move easily.

1) If you push an eraser across a desk, the eraser will move for a short distance and then stop. 2) When you move a heavy dresser by pushing it along the floor.
Remove everything in the refrigerator to lighten the load. Put a lubricant between the surface of the object and the floor. use round objects, like pencils, to decrease the friction and push the refrigerator oover the pencils more easily
