Sliding friction acting between two surfaces is always less than static friction acting between the same two surfaces. Why?

Explanation

To understand why sliding friction is always less than static friction between two surfaces, we can break down the explanation into a few key steps:

### Step 1: Definition of Static Friction
Static friction is the force that keeps two surfaces at rest relative to each other. It acts to prevent motion between the surfaces.

**Hint:** Think about how hard it is to start moving a heavy object that is not moving at all.
