Question

Give any 2 examples for the ways of reducing friction?​

Answer 1

Following are few ways by which friction can be reduced :

1. To reduce friction, we must make the surface more smoother. It is because a surface which is of rough type results in more amount of friction. Whereas the smoother surface leads to reduction in friction.

For example : we can lubricate a surface to which will help in reducing the friction.

2. Another way to reduce friction is by making the object more streamlined. This type of object offers very minimum resistance and thus reduces friction.

Answer 2

Lubricating a surface to make it smoother and by reducing the contact between surfaces, we can reduce friction.

Explanation:

• Friction holds object in its place otherwise it would slide. But if there is more friction then it would slow down the movement and would make the surface weary.
• Friction is used in our daily life to hold something to a surface, one of such examples is- grip of shoes on the ground while moving.
• There are certain ways in which we can decrease the amount of friction.
• One of them is to make the rough surface smooth by applying lubricant.
• The other way is to make less contact between the object and the surface.
