Question

Give two ways to reduce friction.​

Answer 1

Answer:

Make the surfaces smoother. Rough surfaces produce more friction and smooth surfaces reduce friction.

Lubrication is another way to make a surface smoother. A lubricant is a slippery substance designed to reduce the friction between surfaces. 

Make the object more streamlined. A streamline shape is one that allows air or water to flow around it easily, offering the least resistance.

Answer 2

Answer:

$\huge\tt\underline\red{answer}$

Ways to reduce friction:

• make the surface smoother.rough surface produce more friction and smooth surface reduces friction.
• lubrication is another way to make surface smoother.
• make the object more streamlined.
• reduce the force acting on the surface.
• reduce the contact between the surface.
• friction can also be reduced by switching from sliding friction to rolling friction.

★more information about the topic:

▶️Friction is a force between two surfaces that are sliding, or trying to slide, across each other. For example, when you try to push a book along the floor, friction makes this difficult. Friction always works in the direction opposite to the direction in which the object is moving, or trying to move.
