Work done in free space

    If we apply force on a small mass in open space, then it will cover infinite displacement. Then would the mass have infinite work done?

    The work only takes into account the distance over which the force is applied. Once the force stops acting, the work doesn't increase.

    "Work" is energy. In your example, the energy is finite: namely the kinetic energy of the mass.
