Pendant vs. Pendulum — What's the Difference?
By Fiza Rafique & Maham Liaqat — Updated on May 5, 2024
Pendant is a piece of jewelry that hangs from a chain worn around the neck, while a pendulum is a weight suspended from a pivot so it can swing freely.

Key Differences
A pendant typically serves as an adornment or a decorative accessory, often seen hanging from necklaces or earrings. Whereas, a pendulum is primarily used in scientific and time-keeping applications, such as in clocks and various measuring instruments.
Pendants are made from a wide range of materials including metals, gemstones, and glass, designed to add aesthetic value to personal jewelry. On the other hand, pendulums are usually made from a uniform material like metal or wood, focusing more on their weight and balance rather than appearance.
In jewelry, the design of a pendant can symbolize cultural, personal, or religious meanings, playing a significant role in fashion and identity expression. Meanwhile, the design of a pendulum is often simple and functional, optimized for its ability to swing with minimal resistance and consistent period.
The size and weight of pendants vary broadly, tailored to the style and preference of the wearer, without much restriction on dimensions. Conversely, the dimensions of a pendulum, particularly its length, are critical to its function, directly influencing its oscillation period.
While pendants are primarily static objects that do not perform any mechanical function, pendulums are dynamic, integral to the operation of mechanisms they are part of, such as clocks, demonstrating the principles of harmonic motion.

Pendant
A pendant is a loose-hanging piece of jewellery, generally attached by a small loop to a necklace, which may be known as a "pendant necklace". A pendant earring is an earring with a piece hanging down.
Pendulum
A pendulum is a weight suspended from a pivot so that it can swing freely. When a pendulum is displaced sideways from its resting, equilibrium position, it is subject to a restoring force due to gravity that will accelerate it back toward the equilibrium position.
Pendant
Something suspended from something else, especially an ornament or piece of jewelry attached to a necklace or bracelet.
Pendulum

What are common shapes for pendants?
Common pendant shapes include hearts, crosses, teardrops, and geometric figures.
What scientific principles can be demonstrated with a pendulum?
Pendulums are used to demonstrate principles such as gravitational force, harmonic motion, and periodicity.
How is the length of a pendulum important?
The length of a pendulum affects its oscillation period; the longer the pendulum, the slower it swings.
What types of clocks use pendulums?
Many traditional clocks like grandfather clocks, mantel clocks, and some wall clocks use pendulums.
How does the weight of a pendant affect its use?
The weight influences how it hangs and can affect the comfort and look of the necklace.
How precise are pendulum measurements?
Pendulum measurements can be extremely precise, especially in controlled scientific environments.
How does a pendulum work?
A pendulum works by gravity pulling it down and inertia causing it to swing upward, creating a steady, repeatable motion.
Can a pendant be part of a larger piece of jewelry?
Yes, pendants can be integral parts of necklaces, bracelets, or earrings.
Can pendants be functional?
While primarily decorative, some pendants can also function as lockets, containers, or even as tools like magnifying glasses.
