Friction can be observed between two surfaces that are in contact with each other and attempting to move relative to one another. It is a force that resists the motion of objects and causes heat to be generated. Examples include the friction between a car's tires and the road, or between a pencil and a piece of paper.
No, without any external reference points to visually determine movement, you would not be able to perceive that you are moving on a train if there is no friction. The lack of friction would eliminate the physical sensations typically associated with movement.
If there was no friction, your shoelaces would not stay tied, as friction between the laces and knots is what keeps them in place. Without friction, the laces would easily slip and come undone.
If there was no friction, the pieces of wood nailed together would not be able to stay in place. Without friction, there would be nothing to prevent the pieces from sliding and slipping out of position. Therefore, the structure would likely fall apart.
Two rough surfaces with high friction coefficients would have the highest coefficient of friction. For example, rubber on concrete or sandpaper on wood would typically result in a high coefficient of friction due to the roughness of the surfaces.
No, a box will not be able to slide on a smooth floor with no friction. In the absence of friction, there would be no force to overcome the box's inertia and initiate its motion. Without friction, the box would remain stationary.
NO friction
A synonym for friction would rub. :DA synonym for friction would rub. :D
It is impossible to have no friction. If there was no friction we would be sliding all over the place, nothing would be balanced.

When the wheels of a car turn, friction causes the wheels to push back on the road, which in turn causes the road to push the car forward. Without friction the wheels would just spin in place. You can sometimes see this occur on icy roads, where there is very little friction.
Yes it would, thank God for rolling friction
No. friction produces thermal energy therefore friction produces heat. Rub your hands together and see what happens.
when you slide across a surface and then see an affect after.

Friction is fascinating because in so many situations we try to reduce friction, but friction is a necessary force, without which everything would be impossible. Without friction we would all be flat on the floor without any methods of directing our motion. We would randomly collide with things and then continuing moving in another direction. Without friction the slide at the playground would be really fast, but you could never climb the ladder to get on it. The swings would be useless since no one could get into them. So friction is necessary for playgrounds.
