Calculates the escape velocity needed to break free from a celestial body's

Module Contents

physics.escape_velocity.escape_velocity(mass: float, radius: float) → float

Calculates the escape velocity needed to break free from a celestial body’s gravitational field.

The formula used is:

v = sqrt(2 * G * M / R)

where:

v = escape velocity (m/s) G = gravitational constant (6.67430 * 10^-11 m^3 kg^-1 s^-2) M = mass of the celestial body (kg) R = radius from the center of mass (m)

Args:

mass (float): Mass of the celestial body in kilograms. radius (float): Radius from the center of mass in meters.

Returns:

float: Escape velocity in meters per second, rounded to 3 decimal places.

Examples:

>>> escape_velocity(mass=5.972e24, radius=6.371e6)  # Earth
11185.978
>>> escape_velocity(mass=7.348e22, radius=1.737e6)  # Moon
2376.307
>>> escape_velocity(mass=1.898e27, radius=6.9911e7)  # Jupiter
60199.545
>>> escape_velocity(mass=0, radius=1.0)
0.0
>>> escape_velocity(mass=1.0, radius=0)
