Is friction zero on smooth surface?

No, exactly zero friction isn’t possible practically. Friction is always more on a rough surface compared to a smooth surface. This is because rough surface offers more resistance to the movement of an object over it compared to a smooth surface.

Does smooth surface have friction?

Friction is LESS on smooth surface, hence the roller travels a greater distance on smooth surface compared with the rough surface. contact. Even those surfaces which appear very smooth have a large number of minute irregularities on them. Irregularities on the two surfaces lock into one another.

Why there is no place with zero friction?

These orbiting bodies can be a planet and its satellite , a star and any object orbiting it, or components of any binary system . Orbits do not decay without some friction-like mechanism which robs energy from the orbital motion. This can be any of a number of mechanical , gravitational , or electromagnetic effects.

Why is friction more on a smooth surface?

A rough surface will have more friction because on the rough surface there will be more irregularities. They will cause interlocking which in turn creates more frictional force. For a smooth surface, irregularities and interlocking is less and hence has very less friction. So it can move easily.

Why is there less friction on smooth surfaces?

Answer: Smooth surface have less friction because smooth surface have less resistance than rough surface. smooth surfaces have less irregularities that stop the moving object whereas rough surfaces have more irregularities.

Which surface have more friction rough or smooth Why?

A rough surface will have more friction because on the rough surface there will be more irregularities. They will cause interlocking which in turn creates more frictional force. For a smooth surface, irregularities and interlocking is less and hence has very less friction.

Which surface has more friction rough or smooth?

Answer : A rough surface will cause more friction than a smooth surface. Because, rough offers more resistance to the other surface in contact as compared to the smooth surface.

Which place in the universe has no friction?

One of the most fundamental tenets of modern physics is that in a perfect vacuum – a place entirely devoid of matter – no friction can possibly exist, because empty space cannot exert a force on objects travelling through it.

Why does a smooth surface have less friction?

Which has less friction road surface or smooth surface?

Rough surfaces have more friction than smooth surfaces and liquids such as oil or water are sometimes used as lubricants to reduce the effect of friction. There is no mystery behind friction. It acts on objects at the surfaces so as to prevent or reduce movement between the surfaces.

What is the smoothest surface with zero friction?

Smooth surfaces have LESS friction, not MORE. Technically, no surface has zero friction. But ICE and TEFLON come pretty close. They are the two smoothest surfaces I know of and they certainly have LESS friction. But then, the answer would be what I said previously.

What happens when two surfaces of the same material are smooth?

Although this is difficult to achieve in practice – it is annoying when you don’t want it to happen. If the two surfaces of the same material are very smooth, the molecules and atoms of one surface get closer to the molecules and atoms of the other surface.

How does the smoothness of a surface affect the friction force?

As the smoothness of the surface increases the molecular interaction (vander walls force) increases resulting in the increment of Frictional force. What’s something I can do right now to increase my productivity? A tool you can leverage to instantaneously improve your productivity is a writing assistant.

What is the cause of dry sliding friction?

His work with Taylor explored the theory that dry sliding friction is caused by shearing at junctions formed at regions of contact, known as the real area of contact, between the sliding surfaces. Depending on the type of roughness and the materials’ properties, the real area of contact does not necessarily depend on the average surface roughness.
