## Unbalanced Force Model

In this model we will be studying forces on objects that are not balanced and how this affects the motion of the object. Students will be able to determine the acceleration, distance, time, and friction for objects with unbalanced forces among many other things!

## Standards

UBFM1 - I can use multiple diagrams to represent an object with unbalanced forces.

UBFM2 - I can draw quantitative vector addition diagrams that show unbalanced forces.

UBFM3 - I can solve problems using Newton's 2nd law.

UBFM2 - I can draw quantitative vector addition diagrams that show unbalanced forces.
