Question

what is the escape velocity? Derive the equation for escape velocity on earth surface.​

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.

• From this equation, it can be said that the escape velocity depends on the radius of the planet and the mass of the planet only and not on the mass of the body. Escape Velocity of Earth= 11.2 km/s. This was the derivation of the escape velocity of earth or any other planet.

Answer 2

Answer:

Answer♡⋆

Escape velocity is the minimum velocity that a body must attain to escape the gravitational field of the earth. Suppose if we throw a ball,it will fall back.
