# Centripetal Acceleration

## Objects moving in a circle must experience acceleration and force perpendicular to their direction of travel.

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.

## Centripetal Acceleration

Students will learn what is centripetal acceleration, where it applies and how to calculate it. Students will also learn when a force is acting as a centripetal force and how to apply it.
