pls answer me fast very urgent dont be spam ,answer the all questions ,if you spam i will delete the question
Answers
Answer:
1. lubricants
2. reduces
3. high.
4. friction
5. We pour few drops because this will reduce the friction between the door making it easier to open and close and also reduces the sound produced.
6. Some ways are to make the surface smoother, lubricate it, reduce the force etc.
7. Lubricants effect friction as when applied fill up the irregularities due to which interlocking of irregularities becomes less and thereby friction is reduced.
explanation:
Answer:
what is friction ?
☆ interlocking between 2 surfaces.
☆ Friction is a force that holds back the movement of the object.
_____________________________________
1) Lubricants
- the substances which reduce friction are called lubricants .
- it reduces the friction by getting filled inside the rough surfaces.
_____________________________________
2) reduces friction
- on sprinkling of powder , the soft powder gets filled on the rough surfaces. thus , makes the surface soft and smooth.
_____________________________________
3) more
- on rough surfaces, the friction is more as the rough surfaces cause more interlocking between them . hence , responsible to increase of friction.

4) friction.
- as we know , the interlocking between surfaces are called friction.

5) to reduce friction.
- on pouring the oil on the surface of doors , the oil soften the surface of the door and the force decreases and the door will not produce sounds.

6) ways to reduce friction :-
☆ applying lubricants such as :-
- powder .
- oils .
- paints.
- water .
- small pebbles.
- tiny small particles or sands .

7) affect of lubrication :-
- lubrication provides less force , as it is responsible to reduce friction, the frictional force gets negligible.
- due to this we can do many works easily.
- energy is less consumed.
