Final answer:
When work is done, a transfer of energy always occurs.
Step-by-step explanation:
When work is done, a transfer of energy always occurs. Work is defined as the transfer of energy from one object to another through the application of a force over a distance. This means that whenever work is done, energy is being transferred. For example, when you lift a book off the ground, you are exerting a force and transferring energy to the book to increase its gravitational potential energy.
