Oil and grease are viscose (thick) liquids. They cling to the surfaces of metals easily, which allows the surfaces to 'glide' past each other without rubbing.

What kinds of substance reduce friction?

Friction is the act of one surface rubbing against another. To reduce friction, use something that offers a small amount of friction. Smoother substances reduce friction. A way to reduce friction is to use something which offers a small amount of friction. For example, you could use something like plastic or glass. Water, most liquids and different types of oil reduce friction. Powder, oil and grease are used in between surfaces to also reduce friction.


What is one way you can reduce friction?

You can reduce friction by using lubrication, like grease for bearing, sewing machine oil etc.


Material that is applied to reduce friction?

Oil (in car). Grease (in bearings). Silicon. Water.


Why is grease used in machine?

Grease and oil is used in machinery to prevent the moving parts from wearing out too soon due to friction.


The use of oil or grease to lessen friction is called?

The use of oil or grease to lessen friction is called lubrication. Lubrication helps to reduce friction between two surfaces in contact, allowing for smoother movement and improved efficiency.


What can you do to reduce the amount of friction between two objects?

You can reduce friction between two objects by using lubricants such as oil or grease, polishing or smoothing the surface of the objects, or using ball bearings or rollers in between the objects to minimize direct contact. Additionally, lowering the force pressing the objects together can also reduce friction.


What material can reduce friction?

Materials that can reduce friction include lubricants such as oil, grease, and wax, as well as low-friction materials like Teflon and graphite. Using smooth surfaces or adding ball bearings can also help reduce friction.


How can you reduce the amount of friction on moving parts?

You can reduce friction on moving parts by using lubricants such as oils or grease to create a slippery layer between the surfaces. Proper maintenance and alignment of the parts can also help reduce friction. Using materials with lower coefficient of friction or adding bearings and bushings can further minimize friction.


What is the use of oil or grease to lessen friction is called?

The use of oil or grease to lessen friction is called lubrication. Lubrication helps to reduce wear between moving parts, improve efficiency, and prolong the lifespan of machinery or equipment.
