Product Code : SCL-SK-12145
Newton’s Third Law Model lab (SKU SCL-SK-12145) is a physics teaching apparatus for showing that forces always act in pairs: action and reaction are equal in size and opposite in direction. It suits recoil, push-off and collision demonstrations in school physics labs, college practicals and STEM classes. Science Lab Supplies manufactures the model on its own shop floor at Plot 448, HSIIDC Industrial Area, Saha, Ambala, India, and sells it to schools, colleges, tender contractors and distributors without an intermediary.
Specifications
The table shows the specification of the third-law model. In short, it makes force pairs visible by letting two bodies interact, for example through a spring release or a collision, so that each pushes on the other; construction, materials and any force meter or trolleys are confirmed on the quotation.

Applications and Experiments for the Newton’s Third Law Model
Students can predict how two bodies will move after a controlled push or spring release, watch both move off in opposite directions, and link what they see to equal and opposite forces. The model supports the laws-of-motion chapters of school physics and introductory college mechanics.
- Class 9 and Class 11 physics (NCERT): Newton’s third law of motion.
- Recoil and push-off, such as the recoil of a gun or a swimmer pushing off a wall.
- Showing that two hooked force meters read the same when pulled against each other, using a pair of 0–20 N Mechanical Dynamometer with Upper and Lower Hooks or meters from the Set of Spring Force Meters with Different Ranges.
- Collisions and conservation of momentum as an extension topic.
Standard Scope of Supply
The Newton’s Third Law Model lab is supplied as one demonstration set as described above. Parts such as trolleys, a track, springs, buffers, masses or a force meter depend on the version offered, so the quotation names each item and states whether measuring accessories are part of the set.
Packing, MOQ and Lead Time
Quotations are prepared for one model or for a number to equip several physics rooms. They state packing, delivery time and price for the quantity requested, and other science kits for students in India, such as the first and second law apparatus, can be included.
As a registered exporter with an Importer-Exporter Code, Science Lab Supplies can ship to buyers in Kenya, Ghana, Ethiopia, Tanzania, Uganda and the UAE. For a third-law model quotation, message the team on the contact page, add several items to the enquiry cart, or go through the lab tender page for public tenders.
Frequently Asked Questions
What does Newton’s third law state?
When one body exerts a force on another, the second body exerts a force of equal size in the opposite direction on the first. The model shows this by making both bodies move.
Can the model show recoil motion?
Yes, where the version offered includes two moving bodies or a spring-release mechanism. The quotation confirms the parts, so you can check the recoil setup before ordering.
Who manufactures this model?
The third-law model is built by Science Lab Supplies at its factory in Saha, Ambala, India. There is no trader between you and the maker, and your quotation is drawn up at the factory.
Is it safe for students?
Yes, with teacher supervision. Do not overload springs, release trolleys toward people or place fingers near moving parts, and replace damaged tracks, cords or springs.
