# S4P3: Balanced and Unbalanced Forces

Obtain, evaluate, and communicate information about the relationship between balanced and unbalanced forces.

- Subject: Science
- Appears in: Grade 4, https://georgiahomeroom.org/standards/science/grade-4.md

## Expectations

- **S4P3.a**: Plan and carry out an investigation on the effects of balanced and unbalanced forces on an object and communicate the results.
- **S4P3.b**: Construct an argument to support the claim that gravitational force affects the motion of an object.
- **S4P3.c**: Ask questions to identify and explain the uses of simple machines (lever, pulley, wedge, inclined plane, wheel and axle, and screw) and how forces are changed when simple machines are used to complete tasks.

## Georgia Milestones coverage

No Georgia Milestones blueprint cites this standard.
