Give reasons for the following:
A man walking on the street slips on a banana skin.

Explanation

**Step-by-Step Solution:**

1. **Understanding Walking and Friction:**
- When a person walks, they push against the ground with their feet. This action creates a reaction force from the ground that helps them move forward. This is due to the principle of action and reaction as described by Newton's third law of motion.

2. **Role of Static Friction:**
- The force that prevents slipping while walking is called static friction. This frictional force acts in the opposite direction to the motion and allows us to maintain our balance and control while walking.
