# Circular Motion

## The force and acceleration vectors point to the center of the circle.

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.

## Circular Motion

Students will learn that in circular motion there is always an acceleration (and hence a force) that points to the center of the circle defined by the objects motion.
