# How does the friction occur?

## How does the friction occur?

Scientists are not completely sure what causes friction; however it is thought to be caused by the interactions between the tiny bumps on surfaces as they rub against each other. The bumps on each surface bend and exert a force on each other making it hard for the surfaces to slip over each other.

## What must happen for friction to occur?

Friction is a force that occurs when two surfaces slide past one another. The force of friction opposes the motion of an object, causing moving objects to lose energy and slow down. When objects move through a fluid, such as air or water, the fluid exerts a frictional force on the moving object.

## What is friction when and how does it occur?

Friction is the force exerted by the surface of an object when another object moves against it. Friction occurs in the direction opposite to motion, and because of this, it is a force that affects the motion of objects. When you go down a slide, friction works opposite to your downward movement.

## How is friction caused very short answer?

Friction is a force that occurs when two surfaces slide past one another. The force of friction opposes the motion of an object, causing moving objects to lose energy and slow down. When objects move through a fluid, such as air or water, the fluid exerts a frictional force on the moving object.

## How does friction occur Class 4?

Friction is caused by the interlocking of irregularities in the surface of two objects which are in contact with each other. To move one object over the other ,we have to apply a force to overcome interlocking of the irregularities in their surfaces.

## How does friction occur?

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. Friction produces heat because it causes the molecules on rubbing surfaces to move faster and have more energy.

## What are two things friction needs to occur?

There are two main factors that will influence the total amount of friction: 1) the roughness of the surfaces (or the coefficient of friction) and 2) the force between the two objects.

## What is required for a friction force to come into play?

The given object should be at rest being in contact with each other. There should be interlocking and the irregularities on the surface in contact. A force should act on one of the objects and tried to move. Still, the object should remain at rest relative to another surface on an object in contact.

## How did friction occur?

Friction, in simple terms is a force that opposes motion. It occurs when two surfaces are in contact with each other. Friction occurs due to the roughness of the surfaces in contact. A kind of interlocking occurs between the irregularities of the surfaces and hence a resistive force develops.

## What exactly is friction?

friction, force that resists the sliding or rolling of one solid object over another. Frictional forces, such as the traction needed to walk without slipping, may be beneficial, but they also present a great measure of opposition to motion.

## Why do frictional forces occur?

Scientists are not completely sure what causes friction; however it is thought to be caused by the interactions between the tiny bumps on surfaces as they rub against each other. The bumps on each surface bend and exert a force on each other making it hard for the surfaces to slip over each other.

## How is friction caused short answer?

Friction is caused due to the irregularities of the surfaces in contact. When the two surfaces are moved against each other these bonds resist the motion creating friction. Roughness of surfaces is also a reason for friction. No matter how smooth a surface looks, it has some irregularities.

## How is the friction caused?

Scientists are not completely sure what causes friction; however it is thought to be caused by the interactions between the tiny bumps on surfaces as they rub against each other. The bumps on each surface bend and exert a force on each other making it hard for the surfaces to slip over each other.

## What is friction how it is caused Class 8?

Friction is caused by the interlocking of irregularities in the surface of two objects which are in contact with each other. To move one object over the other ,we have to apply a force to overcome interlocking of the irregularities in their surfaces.

## What is friction short answer?

Friction is a force between two surfaces that are sliding, or trying to slide, across each other. Friction always works in the direction opposite to the direction in which the object is moving, or trying to move. Friction always slows a moving object down.

## What causes friction Class 4?

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. Friction produces heat because it causes the molecules on rubbing surfaces to move faster and have more energy.

## How do you explain friction to a child?

The interlocking of the depressions and elevations (irregularities) present on the surfaces of the bodies in contact cause friction.

## What are the 2 main causes of friction?

The causes of the resistive force of friction are:

• Surface Roughness.
• Plowing effect.

## What are the 2 factors that affect the friction of objects?

Friction is a force that occurs when two surfaces slide past one another. The force of friction opposes the motion of an object, causing moving objects to lose energy and slow down. When objects move through a fluid, such as air or water, the fluid exerts a frictional force on the moving object.

## Which two conditions which are necessary to have more friction?

The strength of the force of friction depends on two factors; the type of surfaces involves and how hard the surfaces push together, What is one way you could reduce the friction between two surfaces? Ball bearing are one way of reducing friction between two surfaces.

## What does force of friction come into play?

Friction comes into play when irregularities present in the surfaces of two objects in contact get interlocked with each other. Static friction comes into play when we try to move an object which is at rest. Sliding friction comes into play when an object slides over the surface of another object.

## What is the required for a force to come into play?

At least two objects must interact for a force to come into play. Thus, an interaction of one object with another object results in a force between the two objects and no physical contact is necessary.

## What are the necessary conditions for friction?

being in contact with each other. 2)There should be interlocking of irregularities on the surface in contact. 3)A force should act on one of the objects and tried to move. 4)Still object should remain at rest relative to another surface on object in contact.
