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.
