Explain why, sliding friction is less than static friction.

Explanation

To explain why sliding friction is less than static friction, we can break down the explanation into several steps.

### Step-by-Step Solution:

1. **Definition of Friction Types**:
- **Static Friction**: This is the frictional force that prevents an object from starting to move when it is at rest. It acts on an object that is not moving relative to the surface.
- **Sliding Friction**: Also known as kinetic friction, this is the frictional force acting on an object that is already in motion relative to the surface.
