Question

What kind of substance are known as Lubricants. (a) increase friction (b) decrease friction (c) increase or decrease friction( d) none of these​

Answer 1

Answer:

Lubricants like oil and grase help in decreasing friction.

For eg-We apply oil to the chain of our bags if they got stuck. In this way friction is decreased and it works smoothly.

Plz and Plz mark my answer brainliest.

Answer 2

The correct answer is: (option b) decrease friction.

• A lubricant is a material that goes between two surfaces that are in contact to decrease friction.
• When applied between the two surfaces, oil, grease, and graphite will lessen friction and smooth out movement. Therefore, it is possible to classify all of these substances as lubricants.
• Lubrication lessens friction and wear by adding a friction-reducing layer between moving surfaces in contact. The substance that is utilized as a lubricant can be liquid, solid, or plastic.

Therefore, (option b) decrease friction is the correct answer.

Additional Information:

• The force that prevents an object from sliding against another is known as friction. Friction causes items to move more slowly before finally coming to a stop. It is possible to move against a surface while walking or driving thanks to friction, which is not necessarily a bad thing. Moving would not be feasible on Earth without friction.
