The Physics of Escape Velocity

Escape velocity is the minimum speed needed for a free, non-propelled object to escape from the gravitational influence of a primary body. For example, to leave Earth permanently, a rocket must reach about 11.2 km/s.

G: Universal Gravitational Constant (6.67430 × 10⁻¹¹ m³/kg·s²).
M: Mass of the body.
R: Distance from the center of the body.

Formula: v = √(2GM/R)

Note that escape velocity depends only on the mass and radius of the planet, not on the mass of the escaping object.
