Conservation of Angular Momentum Manufacturer,Supplier and Exporter in India
Product Code : EL-ELA-5514
Jlab Export is a leading Conservation of Angular Momentum Manufacturer,and suppliers in India
Conservation of Angular Momentum (code EL-ELA-5514) is a demonstration apparatus in which a hand-spun arm on a vertical board carries two weights that a pull cord draws in towards the centre, so the spin visibly speeds up. It is for visual demonstration only, with no measurements intended, and an instruction manual is provided. It is made by Jain Laboratory Instruments Pvt Ltd (JLab) at its works in Ambala, India.

What Is the Conservation of Angular Momentum Apparatus Used For?
Conservation of linear momentum is usually demonstrated in class, but its rotational counterpart is just as important and harder to show with a meaningful experiment. This apparatus makes it visible. Angular momentum is the product of the moment of inertia and the angular velocity, and with no outside torque it stays constant; pulling the weights inwards reduces the moment of inertia, so the arm has to spin faster. It is the same effect an ice skater uses in a pirouette, spinning with arms outstretched and then turning much faster as the arms are drawn in.
The demonstration suits rotational-motion lessons in class 11 physics, introductory mechanics in college and university physics, and engineering science and applied mechanics classes in degree and diploma courses, where the teacher or a student pulls the cord in front of the group.
Frequently Asked Questions
What does the apparatus demonstrate?
That angular momentum is conserved: when the two weights on the spinning arm are pulled towards the centre, the moment of inertia falls and the angular velocity rises noticeably.
How is it operated?
The weights are moved to the outer ends of their travel, the arm is spun rapidly by hand, and the weights are then pulled towards the centre with the cord, by a student or the demonstrator.
Can it be used to take measurements?
No. It is listed for demonstration only, with no measurements intended; it is designed for clear visual observation of the effect.
Is an instruction manual provided?
Yes. A complete instruction manual describes the apparatus, its application, the experimental procedure and typical test results.
What information is needed for an export quotation?
Send the quantity, the destination country and port or city, your preferred delivery terms (for example FOB or CIF), any packing or labelling needs, and the tender reference if the order is for a tender.
Who manufactures this apparatus?
Jain Laboratory Instruments Pvt Ltd, trading as JLab, makes it at its works in Ambala, Haryana, India, and quotes for it directly.
OEM Manufacturer
JLab is the trading name of Jain Laboratory Instruments Pvt Ltd, a physics and engineering teaching equipment manufacturer in India, incorporated in 2017 and based on Hargolal Road, Ambala, Haryana. The apparatus is made at JLab’s own works, not bought in from a trader, so schools, colleges, dealers and importers order it factory-direct, every unit is visually inspected before dispatch, and repeat orders are handled by the manufacturer. JLab exports worldwide and ships to buyers in every region — for example Guyana in South America, Belgium in Western Europe, Uzbekistan in Central Asia, Tunisia in North Africa and Rwanda in East Africa. Tender buyers can refer to the JLab lab tenders page.
