# Electric Fields

## Electric fields are used to keep track of forces that charged particles feel.

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.

## Electric Fields

Students will learn what an electric field is, how to draw electric field lines and how to calculate electric fields. They will also learn to apply the electric field in order to find the direction a charge would move.
