Question

1. list 3 to 5 ways to reduce friction.

Explanation:

Friction can be reduced by using lubricants (e.g., oil, grease) to separate surfaces. Polishing surfaces to make them smoother also reduces friction. Using rollers or ball - bearings converts sliding friction to rolling friction, which is less. Streamlining shapes (in fluid - friction cases) reduces resistance.

Answer:

1. Use lubricants.
2. Polish surfaces.
3. Use rollers/ball - bearings.
4. Streamline shapes (for fluid friction).
