9.1 Work, Power, and the Work–Energy Theorem - OpenStax
WEBWork and energy are closely related. When you do work to move an object, you change the object’s energy. You (or an object) also expend energy to do work. In fact, energy can be defined as the ability to do work. Energy can take a variety of different forms, and one form of energy can transform to another.
