Explanation

Once the wrench is thrown in space, it will continue moving indefinitely without any additional force needed. This is Newton's first law of motion in action - in the vacuum of space with negligible forces acting on it, the wrench will maintain its velocity without requiring force to 'keep it going'. The force was only needed to throw it initially, not to maintain its motion.
