Question

Expalain how we can increase or decrease the friction with example

Answer 1

Answer:

we can increase the increase the friction by :

making the surface rough

decrease the friction by:

adding lubricants like grease, oil...

Answer 2

Answer:

Here is your Answer

Explanation:

You can easily reduce friction by lubricating the two surfaces in contact. You can do this by either applying wax or oil between the surfaces.

You can add wheels or rollers between two surfaces.

Smoothen the surfaces in contact.

You can reduce the weight of the one of the object. (Normal contact force is proportional to friction, and finding the kinetic friction or static friction of the object would ease your calculations.)

IF you want to increase friction,

Increase normal force of one of the object ( Easily by making it heavier )

Roughen the surface

Change the material types (e.g rubber to rubber has higher friction than metal to metal)
