Why do we easily slip on a rainy day ?

Explanation

**Solution:**

1. **Understanding Friction**: Friction is the force that opposes the relative motion between two surfaces in contact. It is essential for walking and maintaining grip on surfaces.

2. **Effect of Rain**: On a rainy day, water accumulates on the ground. This water creates a thin layer between the surface of the ground (like pavement or roads) and our shoes.

3. **Water as a Lubricant**: Water acts as a lubricant. When a lubricant is present, it reduces the friction between the surfaces in contact. In this case, the water reduces the friction between our shoes and the wet ground.
