1. Watch or Launch
Launch the Interactive
Open the simulation, adjust the controls, and compare what changes on screen before answering the concept-check questions.
2. Big Ideas
Key idea Newton's laws connect forces to changes in motion. Balanced forces produce no acceleration, while an unbalanced resultant force causes acceleration in the direction of the resultant force.
What Students Can Learn
- Distinguish balanced forces from unbalanced resultant force.
- Use F = ma to connect force, mass, and acceleration.
- Recognise that motion can continue even when resultant force is zero.
- Use force diagrams and motion evidence together.
Guiding Question
Is the object's motion explained by balanced forces or by a non-zero resultant force?
3. Try the Investigation
Identify Forces
List the forces acting on the object before changing a control.
Predict Acceleration
Use the expected resultant force to predict the motion change.
Run and Compare
Observe velocity or acceleration evidence and compare it with the prediction.
Apply F = ma
Explain how changing force or mass changes acceleration.
4. Teacher Notes
Lesson Use
Use this as a force-to-motion lesson rather than a vocabulary exercise.
Discussion Prompts
Ask: Can an object move with zero resultant force? What changes when resultant force is non-zero?
Teaching Moves
Insist on a force diagram before a motion claim.
5. Concept Check
These questions are generated from the topic and the concept illustrated by the simulation. Use them after students have explored the model.

Expert Challenge
Unlocks after 3 correct concept-check answers on this page.
1. A box moves at constant velocity on a rough horizontal floor while being pushed. What is the best force diagnosis?
2. For the same resultant force, a larger mass has smaller acceleration. Which law is being used?
3. A student says a moving object must have a force in the direction of motion. What is the best feedback?
4. In a free-body diagram, why should the resultant force not be drawn as an extra force acting on the object?
5. A lift accelerates upward. What happens to the normal reaction on a person compared with their weight?
