rough tires get more traction thus, like sliding.
Assuming you're talking about the tyres... The tread on the tyres channels water away from the wheels - allowing the tyres to grip the road better than if the tyres were completely smooth.
The rough surface is better than the smooth surface for the frictional force to act.
Tiles with a rough surface provide more traction and grip, reducing the risk of slipping or falling, especially in wet areas. The texture on rough tiles helps to increase friction, making them safer to walk on compared to smooth tiles which can be slippery, particularly when wet. The rough surface of tiles also disperses water and allows for more secure footing, making them a better choice for areas where slip-resistance is important.
rough sex is good, but smooth sex is better so it cannot hurt anybody!
It all depends. A knobbly tyre will have a poorer grip on a smooth surface than a smooth tyre, while a smooth tyre will have poorer grip on a loose surface than a knobbly tyre. But overall a smooth-tyred road bike, on a smooth and clean road, can brake and corner harder w/o skidding than a bike with knobbly tires can.
True.
Because there is less traction for an object to grab onto on a smooth surface rather than when an object runs over a rough surface.
Because there is less traction for an object to grab onto on a smooth surface rather than when an object runs over a rough surface.
Because the rough road has more friction, thus expending the balls energy quicker than smooth road with less friction.
Smooth surfaces usually have less friction than rough surfaces because there are fewer irregularities and protrusions that can create resistance when two surfaces rub against each other. This causes objects to slide more easily on smooth surfaces compared to rough surfaces.
Almost always.
Silt has a smooth, fine texture that feels silky between your fingers. It is finer than sand, but coarser than clay.
