🎯 Pendulum Bob – Key Features
High-Precision Mass for Pendulum Experiments
A pendulum bob made of iron or aluminium provides a consistent mass at the end of a rod, enabling accurate investigation of periodic motion, tension forces and gravitational effects in physics lab setups.
-
Available in Multiple Materials and Sizes for Comparative Studies
These bobs are offered in iron and aluminium variants (and sometimes other metals) with diameters like 12 mm, 18 mm, 25 mm, each equipped with a suspension hook to support pendulum experiments.
-
Ideal for Educational Demonstrations and Simple Harmonic Motion
Using different masses and materials helps students explore how mass, length and material influence pendulum period, enabling hands-on learning across mechanics and vibrational physics.
-
Durable Construction with Threaded Hooks for Easy Mounting
Typically composed of iron or aluminium spheres with brass or metal threaded hooks, these laboratory bobs offer robust construction and easy attachment to pendulum rods or stands.
