    I want to ask General Relativity is a force or Its a theory which explains how to space-time curve and space-time tells how to move

    General Relativity is a theory, where mass/energy determines space-time geometry, and space-time geometry determines the paths of free falling objects. In General Relativity gravity can be seen as an inertial force, that appears only in accelerated reference frames. But it is not a direct attractive force interaction, like in Newton's theory of gravity. The difference between Newton and Einstein become clearer when curve-linear coordinates instead of inertial forces are used:
