Reduce the friction . . .
Apply lubricant to the surfaces in contact, or reduce the mutual pressure.

What is the relationship between friction and efficiency of a machine?

The relationship between friction and the efficiency of a machine is when friction increases, efficiency decreases, and vice versa. That is why you can never have 100% efficiency, because there is always at least a little friction. They are inversely proportional, meaning, higher friction equals less efficiency.


Does friction affect stopping distance?

Yes, friction plays a significant role in determining stopping distance. The friction between the tires and the road surface creates the braking force needed to slow down or stop a vehicle. The higher the friction, the shorter the stopping distance, and vice versa.


Methods of increasing and decreasing friction?

To increase friction between two surfaces, you can use materials with a high coefficient of friction or roughen the surfaces. This can be achieved by adding texture or applying substances like sandpaper or rubber to increase the grip. To decrease friction, you can use lubricants such as oil or grease to create a slippery layer between the surfaces, allowing them to slide more easily.


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.


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.
