Answer:-

If we make the sliding surfaces smooth by lubricating etc. the friction can be​ reduced.

• Friction opposes the relative motion of objects. It is mainly demarcated into two types - rolling friction and sliding friction.

• There are many ways in which friction can be minimized.
• Making surfaces smooth by lubricating with oil etc is the most common way to reduce friction.
