Between the earth and the moon, which one has a greater escape velocity ? Give reason.
or, Is the value of the escape velocity from the earth's surface the same as that from the surface of the moon ?

Explanation

Escape velocity from a planet or satellite `v_e=sqrt(2gR)` where g= acceleration due to gravity on the surface of that planet or satellite and R =radius of that planet or satellite . Value of g and R for the earth are much greater than that for the moon. Hence, the escape velocity from the earth.s surface is greater.
