# Combining Forces

## The net force acting on an object is the combination of all of the individual forces acting on it.

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.

## Combining Forces

by Rico Lin //basic

This video discusses net force and how we are able to find it using vectors. It emphasizes net force when an object experiences forces in the same direction and in opposite directions. The concept of net force is then related back to Newton's First Law of motion.
