Calculate Escape Velocity (ev)



Formula

The formula to calculate the escape velocity (ev) is:

\[ ev = \sqrt{\frac{2 M G}{R}} \]

Where:

What is Escape Velocity?

Escape velocity is the speed that an object needs to travel to escape the gravitational pull of a larger body. It is the minimum velocity required to leave the planet without further propulsion.

Example Calculation

Let's consider an example for Earth:

Using the formula to calculate Escape Velocity:

\[ ev = \sqrt{\frac{2 \times 5.972 \times 10^{24} \times 6.674 \times 10^{-11}}{6.371 \times 10^{6}}} \approx 11186 \, \text{m/s} \]

This means that the escape velocity for Earth is approximately 11186 m/s.
