what+is+the+force+of+friction+?+write+any+two+method+to+reduce+friction​

Answer 1

Answer:

The friction force is the force exerted by a surface as an object moves across it or makes an effort to move across it. There are at least two types of friction force - sliding and static friction. Though it is not always the case, the friction force often opposes the motion of an object.

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.

Answer 2

Answer:

Here's Your Answer

Explanation:

1. Friction is the force resisting the relative motion of solid surfaces, fluid layers, and material elements sliding against each other. There are several types of friction: Dry friction is a force that opposes the relative lateral motion of two solid surfaces in contact.
2. (i)By using lubricants: friction increases as the roughness of the surface increases. ...

(ii) Polishing surfaces: It makes the surfaces even and hence reduces friction.
