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:
- Use lubricants.
- Polish surfaces.
- Use rollers/ball - bearings.
- Streamline shapes (for fluid friction).
