Pendulum Set
Product Code : SCL-PL-12347
Pendulum Set (SKU SCL-PL-12347) is a simple-pendulum kit with a 300 x 200 mm angle plate, a 1 m cord, two bobs of different material and a retort stand, for timing oscillations and measuring swing angles quickly and accurately. It fits Class 9 and 11 physics, B.Sc. first-year practicals and teacher demonstrations. As a science apparatus manufacturer in India, Science Lab Supplies makes the set at Plot 448, HSIIDC Industrial Area, Saha, Ambala, and its quotations reach schools, colleges, tender contractors and distributors first-hand.
Specifications
Plate, scale, cord, bobs and stand parts of the pendulum kit are given one per row below. In short, a 300 x 200 mm front plate with a 90°–0°–90° scale sets the release angle on either side, and a steel and a 19 mm aluminium bob hang on a 1 m cord from a nickel-plated rod in a cast-iron base.

Applications and Experiments for the Pendulum Set
The set covers the classic pendulum investigations: how the period depends on length, why it does not depend on bob mass, and how amplitude affects timing. With the angle plate, students release the bob at a known angle each time, which makes repeated readings consistent and comparisons fair.
- Class 9 science: measuring time periods and simple oscillations, with cord lengths checked on a Wooden Ruler 1 Metre.
- Class 11 physics: simple harmonic motion and finding g from a length–period graph, alongside spring work on the Apparatus for Demonstrating Hooke's law (Determination of Elasticity Constant).
- Showing that the period is independent of mass by swapping the steel and aluminium bobs.
- Small- versus large-amplitude swings using the 90°–0°–90° scale.
Standard Scope of Supply
Each Pendulum Set includes the 300 x 200 mm front plate with angular scale, a 1 m cord, a steel ball with hook, a 19 mm aluminium ball with hook, and a retort stand made up of the cast-iron base and the 10 x 600 mm nickel-plated steel rod. A stopwatch can be added to the quotation.
Packing, MOQ and Lead Time
Whether you need one set for a teacher or a set for each bench, send the number and we will quote it. The quotation covers packing, delivery time and price for that quantity, and stopwatches or spare retort stands can be priced with it.
Science Lab Supplies is a registered exporter holding an Importer-Exporter Code, and it can ship to buyers in Uganda, the UAE, Saudi Arabia, Oman, the Philippines and Nepal. Let us know how many benches need a pendulum set via the contact page or the enquiry cart; oscillation apparatus in a tender is dealt with on the lab tender page.
Frequently Asked Questions
Why does the Pendulum Set have two different bobs?
The steel and aluminium balls have different masses, so students can swap them at the same cord length and see that the period does not depend on the mass of the bob.
What is the angular scale for?
The 300 x 200 mm plate is marked 90°–0°–90°, so the release angle can be set and read, and amplitude can be compared on either side.
Is Science Lab Supplies the manufacturer or a trader?
This set is produced in the Science Lab Supplies facility at Saha, Ambala, India, where the company manufactures it, and quotations are prepared by the maker itself rather than a dealer.
Is a stopwatch included?
The set contents have no stopwatch. Timing uses a separate one, such as the digital stopwatches in the related items, which can be added to your quotation for each bench.
