Question

what is escape velocity ???​

Answer 1

Answer:

In physics, escape velocity is the minimum speed needed for a free, non-propelled object to escape from the gravitational influence of a massive body, that is, to eventually reach an infinite distance from it. Escape velocity rises with the body's mass and falls with the escaping object's distance from its center

In physics, escape velocity is the minimum speed needed for a free, non-propelled object to escape from the gravitational influence of a massive body, that is, to eventually reach an infinite distance from it. Escape velocity rises with the body's mass and falls with the escaping object's distance from its center.

$ve = \sqrt{ \frac{2gm}{r} }$

Ve = escape velocity

G = universal gravitational constant

M = mass of the body to be escaped from

r = distance from the center of the mass

Escape velocity equation

It is equal to G = 6.674 × 10-11 N·m²/kg² . where m is the mass of the starting object, and v is the escape velocity.
