This formula calculates the escape velocity from a planet or star.
v esc is the escape velocity
G is the Gravitational Constant
(6.67259 × 10^ -11 newton square meters per square kilogram( 6.673 ✕ 10^ -11 N m^ 2 /kg^2))
M is the mass of the planet or star
R is the radius of the planet or star
This formula was discovered by Isaac Newton. It allows the calculation of Escape Velocity from a planet or star. If a body is moving with this velocity it will escape from the gravitational pull of the planet or star.
This particular formula is of great significance in confirming a black hole. Notice that mass and radius are used in this formula. If an object like the core of a high mass star has enough mass condensed into a small enough region, measured as the radius, then the escape velocity will increase if the mass is high enough and the radius is small enough. In fact, if you were to take the mass of Earth and condense it to the size of a grape, the number you would get for the escape velocity would exceed the speed of light which is 299,792 kilometers/second.
Fucking love this shit!!
