Smooth surfaces offer _____friction, hence, we tend to slip on polished, tiled, wet or oily floors

Options

A. more
B. less
C. neutral
D. no

Answer

**Step-by-Step Solution:**

1. **Understanding Friction**: Friction is a force that opposes the relative motion of two surfaces in contact. The amount of friction depends on the nature of the surfaces and their roughness.

2. **Identifying Surface Types**: Smooth surfaces, such as polished tiles, wet floors, or oily surfaces, have fewer irregularities compared to rough surfaces. This means there is less area for the microscopic bumps and grooves to interlock.

3. **Effect of Smoothness on Friction**: Because smooth surfaces have fewer irregularities, they provide less resistance to motion. This results in a lower frictional force.

4. **Conclusion**: Since smooth surfaces offer less friction, we tend to slip on them. Therefore, the correct answer to the question is "less friction".

5. **Final Answer**: Smooth surfaces offer **less friction**, hence, we tend to slip on polished, tiled, wet, or oily floors.
