What will be the escape velocity of a rocket of mass m if it is launched from surface of earth of radius R and mass M? Don't substitute the values

The escape velocity \( v_{esc} \) is the minimum velocity an object needs to escape the gravitational influence of a massive body (like the Earth) without any further propulsion. The formula for escape velocity from a planet or celestial body is derived using the principle of conservation of energy, and it is independent of the mass of the object itself.

The formula is:

\[
v_{esc} = \sqrt{\frac{2GM}{R}}
\]

Where:
- \( G \) is the gravitational constant,
- \( M \) is the mass of the Earth (or the celestial body from which the object is escaping),
- \( R \) is the radius of the Earth (or the distance from the center of mass of the celestial body to the surface where the rocket is launched).

Notice that the mass \( m \) of the rocket does not affect the escape velocity.

### Key points:
- Escape velocity is independent of the mass \( m \) of the rocket.
- It depends only on the mass \( M \) and radius \( R \) of the Earth.

### Related questions:
1. How does escape velocity change if the mass of the planet increases but the radius remains the same?
2. How does the escape velocity compare between different planets like Earth and Mars?
3. What would happen if the velocity of the rocket is less than the escape velocity?
4. How is escape velocity related to orbital velocity?
5. Can a rocket reach escape velocity in stages, or does it need to achieve it all at once?

### Tip:
Escape velocity does not account for air resistance, so in practice, more energy is required to escape Earth's atmosphere.
