Escape velocity is defined as: The minimum speed that will allow an object to escape a gravitational field with no further energy input. It is the same for all masses in the same gravitational field ie. the escape velocity of a rocket is the same as a tennis ball on Earth.
Jul 23, 2019 · This speed is called escape velocity, since it’s just enough speed to escape the gravitational pull of the Earth. But why is the escape velocity the same, no matter the mass of the object? The reason is that mass and escape velocity are not related.
The escape velocity is the velocity at which a body must travel to escape the influence of an attractive field from a certain point. The escape velocity of a body on the surface of the Earth is independent of its mass.
Escape speed is the minimum speed required to escape a planet’s gravitational pull. A spacecraft leaving the earth’s surface should be going at a speed of about 11 kilometres (7 miles) per second to enter the outer orbit.

Escape Velocityis referred to as the minimum velocity needed by anybody or object to be projected to overcome the gravitational pull of the planet earth. In other words, the minimum velocity that one requires to escape the gravitational field is escape velocity. Basically, it means escaping the land without any chance of falling back. Therefore, an...
Escape velocity refers to the minimum velocity which is needed to leave a planet or moon. For instance, for any rocket or some other object to leave a planet, it has to overcome the pull of gravity. The formula for escape velocity comprises of a constant, G, which we refer to as the universal gravitational constant. The value of it is = 6.673 × 10-...
Question– Suppose the radius of Earth is 6.38 × 106 m and the mass of the planet earth is 5.98 × 1024 kg. Find out the escape velocity from planet earth. Answer– We can find the escape velocity from earth using the escape velocity formula: vescape = 2GMR−−−−√ Thus, when we replace it with figures, we will get: vescape = 2(6.673×10−11N.m2/kg2)(5.98×...

Definition. Escape velocity is the minimum velocity an object needs to escape from the gravitational pull of another celestial body, such as Earth. It depends on both the mass and radius of the celestial body.
Escape velocity is the minimum speed an object must have to break free from a celestial body's gravitational influence without further propulsion. It depends on the mass and radius of the celestial body.
