## What is an example of increasing friction?

By making the surface rough ,friction force can be increased. Examples of increasing friction-the tyres of a motor car and bicycles are made rough to increase the friction . when a ground or surface become slippery after rain or water splashing it is made rough by spreading sand to increase the friction.

## Which factors can increase the friction?

What are the factors affecting friction?

• Roughness/smoothness of the sliding object.
• Roughness/smoothness of the surface.
• Shape/design of the object.
• Normal force acting upon the sliding bodies.
• Dry friction is independent of the surface area of a contact.
• Type of friction involved(rolling/sliding)

## What are 2 ways to decrease friction?

Methods for decreasing friction:

• Make the surfaces smoother. Rough surfaces produce more friction and smooth surfaces reduce friction.
• Lubrication is another way to make a surface smoother.
• Make the object more streamlined.
• Reduce the forces acting on the surfaces.
• Reduce the contact between the surfaces.

## Can friction reduce to zero?

No, we cannot have zero friction surfaces. We can reduce the friction but we can never reduce it to zero because every surface will still have minor in them. A frictionless surface is not possible is not possible because the surface cannot have a zero friction surface.

## What two factors affect friction?

The frictional force between two bodies depends mainly on three factors: (I) the adhesion between body surfaces (ii) roughness of the surface (iii) deformation of bodies.

## Does friction depend on speed?

Friction is a contact force when two surfaces interact. Notice that both of these friction formulas ONLY depend on the coefficient of friction and the normal force. It does not depend the area of contact, it doesn’t depend on the sliding speed.
