8. list 3 to 5 ways to reduce friction.

Answer

Brief Explanations:

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).
