Escape Velocity Formula

Equation for calculate escape velocity is,

$v_e=\sqrt{\frac{2GM}{r}}$

G is the universal gravitational constant (G = 6.67×10−11 m³ kg⁻¹ s⁻²)

M is the mass of the body to be escaped.

r is the distance from the center of mass of the body to the object.

v_e is the escape velocity
