Apparatus for Demonstrating Circular Motion
Product Code : SCL-PL-11809
Apparatus for Demonstrating Circular Motion (SKU SCL-PL-11809) is a simple centrifugal apparatus for measuring the centripetal force on a mass moving in a circle. From the mass, the speed of rotation and the radius, students calculate the force and compare it with theory. It suits Class 11 physics and first-year college mechanics. Manufacturing is done in-house by Science Lab Supplies at Plot 448, HSIIDC Industrial Area, Saha, Ambala, India, with direct supply to schools, colleges, tender contractors and distributors.
Specifications
The set uses three cylindrical metal bodies, a plastic rod and a 1.5 m / 2 m thread. As the mass rotates, a vertically mounted pointer is moved sideways to line up with the pointed tip of the suspended mass, marking its displacement at that speed and giving the radius of the circle.

Applications and Experiments for the Circular Motion Apparatus
The apparatus is used to find the centripetal force F = mω²r on a rotating mass and to show how that force depends on mass, radius and speed. It supports the circular-motion topics of Class 11 and is practical mechanics lab equipment in India for colleges and polytechnics.
- NCERT Class 11 physics (Motion in a Plane): uniform circular motion and centripetal acceleration.
- NCERT Class 11 physics (Laws of Motion): the force needed for circular motion.
- Changing the metal body to compare centripetal force for different masses.
- First-year college mechanics: verifying F = mv²/r from measured values.
Standard Scope of Supply
Supply includes the centrifugal apparatus with its vertical pointer, three cylindrical metal bodies, the plastic rod and a 1.5 m / 2 m thread. Any extras you request, such as a stopwatch for timing rotations, are itemised separately on the quotation.
Packing, MOQ and Lead Time
One set for demonstration or several for group practicals can be quoted, and the quotation states packing, delivery time and price for that quantity. Timing and motion apparatus from this range can be added at the same time.
Science Lab Supplies has an Importer-Exporter Code and is able to ship to buyers in Vietnam, Malaysia, Peru, Egypt, Iraq and Nigeria. Reach us on the contact page, build a list in the enquiry cart, or open the lab tender page for tender supply.
Frequently Asked Questions
How is centripetal force found with this apparatus?
The pointer marks the radius of the rotating mass at a given speed; with the known mass, speed of rotation and radius, the centripetal force is calculated.
How many masses are included?
Three cylindrical metal bodies are included, so students can repeat the measurement and compare results for different bodies.
Is Science Lab Supplies the manufacturer or a trader?
Science Lab Supplies makes the apparatus itself in its factory at Saha, Ambala, India. You deal with the producer, and the quotation is sent from the factory.
Is a stopwatch supplied?
A stopwatch is not listed in the set. If you need one for timing rotations, it can be added to the same quotation.
