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. Science Lab Supplies, a science apparatus manufacturer in India, produces the set at Plot 448, HSIIDC Industrial Area, Saha, Ambala, and supplies it directly to schools, colleges, tender contractors and distributors.
Specifications
The front plate measures 300 x 200 mm and carries an angular scale reading 90°–0°–90°, so the release angle can be set on either side. Two hooked bobs, one steel and one aluminium of 19 mm diameter, hang on a 1 m cord from a nickel-plated steel rod in a cast-iron retort 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.
- Class 11 physics: simple harmonic motion and finding g from a length–period graph.
- 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 is a separate item.
Packing, MOQ and Lead Time

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?
Science Lab Supplies is the maker of this set, which is produced in its Saha, Ambala facility in India; quotations are prepared by the manufacturer itself.
Is a stopwatch included?
No. Timing needs a separate stopwatch, such as the digital stopwatch in the related items, which can be added to your quotation.
