Explanation
Mechanical work plays a crucial role in energy transfer. It is the process of energy being transferred by a force acting over a distance. In particular, for work to occur in the context of physics, a force must cause a displacement of the object. The displacement could be in the direction of the force or against it. When a force moves an object, it's using energy. So, the best description for the energy transfer by mechanical work is 'Energy is transferred by a force moving an object'.
