Lesson overview
What students will learn
- Distinguish balanced forces from an unbalanced net force and predict whether motion should change.
- Plan a fair investigation that changes force or mass one variable at a time while controlling the other conditions.
Key science ideas
- If the net force on an object is zero, its motion does not change because of the forces in the model.
- For the same object, a larger net force produces a larger change in motion.
- For the same net force, a larger mass produces a smaller change in motion.
