Question

Can you think of any example(s) from your life where you use ways of reducing friction?

Answer 1

Explanation:

Following are few ways by which friction can be reduced :

For example : 1.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.

Hope this helps you

Answer 2

In this question, we need to tell the ways of reducing friction.

• A force called friction prevents one thing from moving against another.
• Friction is the force that prevents two solid objects from rolling or sliding over one another. Although frictional forces, such as the traction required to walk without slipping, may be advantageous, they can provide a significant amount of resistance to motion. Automobile engines use about 20% of their output to overcome frictional forces in moving parts.
• The adhesion forces between the contact zones of the surfaces, which are always microscopically uneven, appear to be the primary cause of friction between metals.
• Friction can be decreased by lubricating a surface to make it smoother and by lessening the contact between surfaces.
• Objects are kept in place by friction because without it, they would slide.
• One example of how friction is employed in daily life to keep objects attached to surfaces is the grip that moving shoes have on the ground.
