"The dynamic friction is a little less than the limiting friction ". Why ?

Explanation

To understand why dynamic friction is a little less than limiting friction, we can break down the explanation into several steps:

### Step-by-Step Solution:

1. **Understanding Friction Types**:
- Friction is the force that opposes the relative motion of two surfaces in contact. There are two main types of friction: static (or limiting) friction and dynamic (or kinetic) friction.
- **Static Friction**: This is the frictional force that must be overcome to start moving an object at rest. It is generally higher because the surfaces are not moving relative to each other, allowing for greater interlocking of surface irregularities.
- **Dynamic Friction**: This occurs when the object is already in motion. It is usually less than static friction because the surfaces are sliding over each other.
