How does friction get affected by the nature of surface?

Explanation

### Step-by-Step Solution:

1. **Understanding Friction**: Friction is a force that opposes the relative motion between two surfaces in contact. It is essential to understand that friction is influenced by various factors, one of which is the nature of the surfaces involved.

2. **Weight of the Object**: The weight of the object in contact with the surface plays a significant role in determining the frictional force. Heavier objects exert more force on the surface, leading to increased friction. Conversely, lighter objects exert less force, resulting in reduced friction.

3. **Nature of the Surface**: The texture and characteristics of the surfaces in contact significantly affect friction. Surfaces can be categorized as smooth or rough:
- **Rough Surfaces**: These surfaces have many irregularities or bumps. The presence of these irregularities allows for more interlocking between the surfaces, which increases the frictional force. Thus, rough surfaces tend to produce stronger friction.
