Question

3) what is escape velocity?​

Answer 1

Explanation:

In physics (specifically, celestial mechanics), 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 achieve an infinite distance from it. ... Speeds higher than escape velocity have a positive speed at infinity.

Answer 2

Answer:

$\huge{ \bold{ \red{ \star{answer}}}}$

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 achieve an infinite distance from it. Escape velocity is a function of the mass of the body and distance to the center of mass of the body.
