What are the three units of work?

The three units of work typically refer to the basic measures of work in various contexts, such as physics, education, and project management. In physics, work is defined as the product of force and displacement in the direction of that force, commonly measured in joules. In education, units of work can refer to structured segments of learning, often encompassing objectives, activities, and assessments. In project management, units of work might denote tasks or milestones that contribute to the overall project deliverables.
