# Work

## There are three key ingredients to work - force, displacement, and cause.

Levels are CK-12's student achievement levels.
Basic Students matched to this level have a partial mastery of prerequisite knowledge and skills fundamental for proficient work.
At Grade (Proficient) Students matched to this level have demonstrated competency over challenging subject matter, including subject matter knowledge, application of such knowledge to real-world situations, and analytical skills appropriate to subject matter.
Advanced Students matched to this level are ready for material that requires superior performance and mastery.

## Work

Students will learn that work is simply the transfer of energy into or out of a system. Students will learn how to calculate the work done and how to incorporate it into energy conservation.
