The escape velocity of a body form the earth depends on
(i) the mass of the body.
(ii) the location from where it is projected.
(iii) the direction of projection.
(iv) the height of the location form where the body is launched.

Explanation

The escape velocity is independent of the mass of body and the direction of projection. It depends upon the gravitational potentail at a point from where the body is launched. Since, this potential depends slightly on the latitude and height of the point, therefore, the escape velocity depends slightly on these factors.
