Answer:

Methods for Reducing Friction:

1. Smooth the Surfaces:

  • Slightly smoother surfaces reduce friction, as rough surfaces create more friction.

2. Lubrication:

  • Applying a lubricant, which is a slippery substance, makes surfaces smoother and reduces friction.

3. Streamlining Objects:

  • Creating a streamlined shape for objects allows air or water to flow around them easily, minimizing resistance.

4. Reducing Normal Force:

  • Decrease the normal force between surfaces in contact. Higher normal force increases friction.

5. Minimizing Surface Contact:

  • Reduce the contact area between surfaces to lessen bond formation. Spherical shapes are ideal for reducing friction as they have minimal contact with other surfaces.
