# Why can the object move easily on the smooth surface?

## Why can the object move easily on the smooth surface?

The amount of friction. And how much the object slows down, depends on the type of surface. A smooth surface creates little friction and objects can move over it easily.

## Why is it easier to slide across a smooth surface than a rough surface?

When two surfaces slide against each other, a force called friction makes them stick very slightly together. Smooth surfaces, like ice and glass, are easy to slide over. They create very little friction. Rough surfaces like rock and sand create much more friction, and are easy to grip on to.

Why do smoother surfaces have less friction?

Friction between rough surfaces occurs because, on the microscopic level, the surfaces have high and low area like hills and valleys. A smooth surface has smaller hills and valleys. There are also electrostatic attractions between surfaces, but these are weaker than the physical barriers to sliding.

### Is there friction on a smooth surface?

Friction is a force that opposes motion between any surfaces that are touching. Friction occurs because no surface is perfectly smooth. Rougher surfaces have more friction between them. Heavier objects also have more friction because they press together with greater force.

### How does friction differ in smooth surface from a rough surface?

Why does a rough surface have greater friction than a smooth surface Class 8?

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.

#### Which has more friction the smooth surface or the rough 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.

#### How does friction differ in a smooth surface from rough surface?

Which has less friction surface or smooth surface?

Describing friction 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.

## Why do rough materials have more friction?

A pair of rough surfaces will have more friction than a pair of smooth surfaces, because the “peaks” of one surface can fall into the “valleys” of the other, meaning that to keep moving either something needs to break, or the surfaces would need to push apart briefly.

## Do smoother surfaces always have less friction?

Making a surface rougher or smoother may not always affect the sliding friction. In addition to this, for certain textures and materials, making a surface smoother reduces friction. But elsewhere, rougher surfaces can actually have less friction.

What is smooth surface and rough surface?

rough surface is having lots of irregularities and produce more friction. e.g…a cemented floor. smooth surface is having less no. of irregularities and produce less friction .

### Why do smooth surfaces have less friction than smooth surfaces?

So why do smooth surface have less friction, it’s basically because there is less resistance when they slide over each other. you need to see a micrograph of different surfaces. A “smooth” surface, when examined closely, will appear like a mountain range.

### What happens when a smooth surface glides over a rough surface?

When a surface is smooth, there is little or no resistance to motion when another smooth surface glides over it. However the result will be different if one surface is smooth and the other is rough.

What does a “smooth surface” look like?

A “very smooth” surface, will appear like a grassy meadow. A “very very very smooth surface,” will appear like a field of sandpaper. A “very very very very smooth surface”, will appear like a smooth surface. What happens when you mate a “smooth surface” to a “smooth surface?” The ridges interlock.

#### Why do smooth surfaces have smaller hills and valleys?

A smooth surface has smaller hills and valleys. There are also electrostatic attractions between surfaces, but these are weaker than the physical barriers to sliding. Liquids such as water and oil reduce friction because they keep the two surfaces from contacting each other.
