On which principle is rocket propulsion based?

Explanation

### Step-by-Step Solution:

1. **Understanding Rocket Propulsion**: Rocket propulsion is the method by which rockets move through space. It involves the expulsion of mass in one direction to create a force in the opposite direction.

2. **Key Factors Influencing Rocket Acceleration**:
- **Exhaust Velocity (Ve)**: This is the speed at which the exhaust gases are expelled from the rocket. Higher exhaust velocity results in greater thrust.
- **Rate of Exhaust Ejection (ṁ)**: This refers to the mass flow rate of the exhaust gases. A higher rate of ejection leads to more thrust.
- **Mass of the Rocket (m)**: The mass of the rocket itself affects how much force is needed to accelerate it. A lighter rocket can achieve higher acceleration.
