How to use this Escape Velocity Calculator š¤
There are input fields for Constant of Gravitation \((G)\), Mass of central body \((M)\), Central body Radius \((R)\), and Escape Velocity \((v_e)\). Enter any two inputs and click on Calculate button.
The calculator uses the \( v_e = \sqrt{ \frac{ 2 G M }{ R } } \) formula, substitues given values, and calcuates the missing value(s).
A missing value is calcuated and displayed in the input field. Also, the caculation is displayed under the input section.
What is Escape Velocity?
Escape velocity is the minimum speed that an object needs to escape the gravitational pull of a planet or any other celestial body without further propulsion. If an object reaches this speed, it can move away from the planet indefinitely.
Calculating Escape Velocity
The escape velocity (ve) can be calculated using the formula:
\( v_e = \sqrt{ \frac{ 2 G M }{ R } } \).
In this formula, the parameters are defined as follows:
G: The gravitational constant, a universal constant with a value of approximately \(6.674 \times 10^{-11} \) N(m/kg)2.
M: The mass of the planet or celestial body from which the object is escaping, measured in kilograms (kg).
R: The radius of the planet or celestial body, measured from its center to the point of escape, in meters (m).
