Final answer:
Work is the term given to energy that is transferred as a result of a force applied over a distance. If work is done on an object, it gains energy. If work is done by an object, it loses energy.
Step-by-step explanation:
Work is the term given to energy that is transferred as a result of a force applied over a distance. When work is done on an object, it gains energy. This can be in the form of potential energy, kinetic energy, or both. On the other hand, if work is done by an object, it loses energy.
