It is observed that when a satellite jumps to a lower orbit in the earth's atmosphere, it becomes hot, which indicates some dissipation of energy. But the orbital speed of the satellite increases as it approaches the earth. Why?

Explanation

To understand why a satellite's orbital speed increases as it jumps to a lower orbit, despite experiencing energy dissipation (which causes it to heat up), we can break down the explanation into several steps:

### Step 1: Understanding Orbital Speed
The orbital speed of a satellite in a circular orbit is given by the formula:
\[ V = \sqrt{\frac{GM}{r + h}} \]
where:
- \( V \) is the orbital speed,
- \( G \) is the gravitational constant,
