A satellite revolves around earth under the gravitational force exerted upon it the earth. Does it perform any work ?

Explanation

To determine whether a satellite revolving around the Earth performs any work under the gravitational force exerted upon it, we can analyze the situation step by step.

### Step 1: Understand the Concept of Work
Work is defined as the product of the force applied on an object and the displacement of that object in the direction of the force. Mathematically, it can be expressed as:
\[ W = F \cdot d \cdot \cos(\theta) \]
where:
- \( W \) is the work done,
- \( F \) is the magnitude of the force,
