A body moving on a surface is brought to rest suddenly. What happens to the friction between the two ?

Explanation

**Step-by-Step Solution:**

1. **Understanding the Situation**: A body is moving on a surface and is suddenly brought to rest. This implies that the body was initially in motion and then experiences a force that stops it.

2. **Identifying Friction**: Friction is a force that opposes the relative motion between two surfaces in contact. It acts when there is a relative motion or an attempt to move between the surfaces.

3. **Condition of Rest**: When the body is brought to rest suddenly, it means that it has stopped moving relative to the surface. At this point, there is no longer any motion between the body and the surface.
