A satellite needs no fuel to move round a planet in a stable orbit. Why?

Text Solution

AI Generated Solution

To understand why a satellite needs no fuel to move around a planet in a stable orbit, we can break down the explanation into several steps: ### Step-by-Step Solution: 1. **Understanding Satellite Motion**: A satellite orbits a planet due to the gravitational force exerted by the planet. This gravitational force acts as the centripetal force that keeps the satellite in its circular path. 2. **Direction of Forces**: ...
