Why is sliding friction less than static friction?

Explanation

To understand why sliding friction (also known as kinetic friction) is less than static friction, we can break it down step by step:

### Step-by-Step Solution:

1. **Definitions**:
- **Static Friction**: This is the frictional force that prevents two surfaces from sliding past each other when they are at rest. It acts when a force is applied to an object but does not cause it to move.
- **Sliding Friction (Kinetic Friction)**: This is the frictional force acting between two surfaces that are sliding against each other. It comes into play once the object has started moving.
