Newton's 3rd Law Model
Product Code : SCL-PLE-11655
Quick Answer: The Newton’s 3rd Law Model uses two trolleys or gliders on a graduated track that push apart through spring-loaded plungers or magnetic bumpers, showing that the action and reaction forces between them are equal and opposite.
Last updated: 18 October 2026
Key Features
- Two-trolley or glider system on a graduated track.
- Spring-loaded plungers or magnetic bumpers for the interaction.
- Adjustable mass slots to change the load.
- Low-friction anodised aluminium or high-impact ABS.
- Levelling base with low-friction bearings.
Technical Specifications
| Specification | Value |
|---|---|
| Layout | Two trolleys or gliders |
| Interaction | Spring-loaded plungers / magnetic bumpers |
| Material | Anodised aluminium or high-impact ABS |
| Track | Graduated, with adjustable mass slots |
| Base | Levelling base, low-friction bearings |
How It Is Used
The two trolleys are held together with the plunger compressed and then released, so they spring apart. With equal loads they travel equal distances along the graduated track; adding mass to one makes it move off more slowly, showing equal and opposite forces and the conservation of momentum.
Frequently Asked Questions
How does the Newton’s 3rd Law Model show action and reaction?
Two trolleys or gliders interact through a spring-loaded plunger or magnetic bumpers. They push on each other with equal and opposite forces, which students judge from the distances moved along the graduated track.
