Simple and Compound Pendulums
Product Code : EL-TOMP-11408
Quick Answer: Simple and Compound Pendulums is a pendulum set with a simple pendulum, a choice of two spheres on a cord, and a compound pendulum, a solid rod on a hardened steel knife edge, used to predict and measure periods of oscillation.
Last updated: October 2026
Key Features
- Simple pendulum with a choice of two spheres on a cord
- Adjustable indicator doubles as the pivot point for quick changes of cord length
- Compound pendulum: solid rod pivoting on a hardened steel knife edge on a steel platform
- Additional spherical mass fixes at any position along the rod
- Extra pivot and disc-shaped mass allow use as a reversible, adjustable compound pendulum
Technical Specifications
| Specification | Value |

| Simple pendulum | Two spheres, cord suspension, adjustable pivot indicator |
| Compound pendulum | Solid rod on hardened steel knife edge |
| Extra parts | Spherical mass, extra pivot, disc-shaped mass |
About This Product
Students predict the period of a given pendulum from theory and compare it with timed results, and see how cord length changes the period. With the compound pendulum set up as a reversible pendulum and adjusted until the periods are equal in both arrangements, it gives a value for the acceleration due to gravity. Laboratories and colleges in Estonia, Slovenia, Tajikistan, Italy, Bosnia and Herzegovina and Bahamas can buy the Simple and Compound Pendulums through an export order.
Frequently Asked Questions
How is the compound pendulum used to find g?
Students adjust the positions of its parts until the time period is the same in the standard and reversed arrangements. The pendulum can then be used to find the acceleration due to gravity.
