Question

give 3 methods for each to increase and decrease friction

Answer 1

Hey!!!

We can decrease friction in following ways:

● By polishing the surface.

● By adding lubricants.

● By making the surface smooth.

We can increasee friction in following ways

● By making the surface rough.

● By removing all lubricants.

● By removing streamlined shape of any object

Answer 2

hey mate,,

here's ur answer....


ways to reduce friction:
1)Make the surfaces smoother. Rough surfaces produce more friction and smooth surfaces reduce friction. ...

2)Lubrication is another way to make a surface smoother. ..

3)Make the object more streamlined. 


ways to increase friction :


1).By making the surface rough friction can be increased. 

2).when a ground or surface become slippery after rain or water splashing it is made rough by spreading sand to increase the friction.

3). sports man wears shoes with a better grip to increase friction.


hope it is helpful....
