Gravitational force is ……………and frictional force is a…………….. .

Explanation

To complete the sentence "Gravitational force is …………… and frictional force is a …………….", we need to identify the types of these forces.

### Step-by-Step Solution:

1. **Identify the Type of Gravitational Force**:
- Gravitational force is a type of force that acts between two masses. It is a force that does not depend on the path taken between two points.
- This characteristic defines it as a **conservative force**. In conservative forces, the work done is independent of the path taken and depends only on the initial and final positions.
