And the escape velocity is root-two times the orbit velocity. The escape velocity thus depends on how far the object has already travelled, and its calculation at a given distance takes into account the fact that without new acceleration it will slow down as it travel, due to the massive body's gravity-- but it will never quite slow to a stop. The escape velocity from Earth is about 11.186 km/s (6.951 mi/s; 40,270 km/h; 25,020 mph) at the surface. Short bit of calculus. This is the required expression for velocity of sound in air. Escape velocity = $$\sqrt{\frac{2 (gravitational constant) (mass of the planet of moon) }{radius of the planet or moon}}$$ ∆Ug = mg∆h It's hidden in the new equation. Naturally, the Earth’s escape velocity is much greater than the moon’s, but much less than that of Jupiter, which boasts the highest escape velocity among all the planets, due to its massive size. Escape velocity rises with the body's mass and falls with the escaping object's distance from its center. The majority of the gas particles the lunar rocks release dart upwards at a velocity that is greater than the moon’s escape velocity – the minimum velocity an object must have to escape a celestial body’s gravitational field permanently, or without ever falling back again. The following equation is used to calculate the escape velocity from any planet or large object. For systems of two bodies the term "escape velocity" is ambiguous, but it is usually intended to mean the barycentric escape velocity of the less massive body. Relative escape velocity is defined only in systems with two bodies. 2 K m / s) A 1 1 K m / s Do you see it?
