Students will be able to develop and use models to compare and predict the resulting effects of balanced and unbalanced forces on an object's motion in terms of magnitude and direction. 8.P.2A.2
Content Knowledge Support
- Read and compete interactive science workbook pages 16-21.
Discussion Topics
- 🤔 Think about your favorite activity in the entire world such as playing a sport, spending time with your family, or even using your cell phone. 😎Create a free-body diagram to model the balanced and/or unbalanced forces acting on you during the activity you chose. 💪Be sure to explain how to calculate the net force acting on you during that activity and post a narrative explaining the forces involved and your free-body diagram.
- If you had to live without either balanced or unbalanced forces which would you choose? Explain why using 2 or more specific examples and include an image that has vectors calculating the net force on it demonstrating the forces to support your answer.
Recommended Exercises
Additional Exercises & Extensions
(Level 1) Comprehension
- Classify each of the following net force diagrams as balanced or unbalanced. For each of the four diagrams you classify explain how you know if it is balanced or unbalanced.
2. Take the Compare and Predict Resultant Forces Challenge below:
(Level 2) Application
- Write a short story specifically explaining how balanced AND unbalanced forces have impacted your day so far using 100-200 words.
- Complete the Net Force Challenge Google Form.
(Level 3) Analysis
- Develop and use phet models to compare and predict the resulting effect of balanced and unbalanced forces on an object’s motion in terms of magnitude and direction using this lesson TEMPLATE.
- **SEPUP the Net Force Challenge

(Level 5) Creation
- Create your own balanced and unbalanced MEMES using this assignment TEMPLATE.
- Create a Tik Tok video demonstrating examples of both balanced and unbalanced forces.
Lab Exploration
Additional Explorations
- Investigate pressure using the formula (Pressure = force/area)
Future Learning Connections (9-12)
- Plan and conduct controlled scientific investigations involving the motion of an object to determine the relationships among the net force on the object, its mass, and its acceleration, and analyze collected data to construct an explanation of the object's motion using Newton's second law of motion.
