Six Metal Pendulum Bob Set

Description

Each bob in the set can act as the concentrated mass of a simple pendulum when suspended from a fixed point on a compatible thread and support. Because the six bobs differ in metal (and therefore typically in mass and density), students can compare their oscillation and settle a common misconception in mechanics — that a heavier bob swings faster or slower than a lighter one purely because of its weight.

This set supports practical lessons on simple harmonic motion, pendulum period, and the relationship (or lack of one) between period, mass and material in an idealised simple pendulum.

Care & Maintenance / Safety Note

• Handle bobs carefully to avoid dropping them on feet or work surfaces, given their metal construction.
• Wipe bobs clean and dry after use, especially if handled with sweaty or damp hands, to reduce the risk of tarnishing.
• Check the suspension thread for fraying before each use and replace it if it shows wear.
• Store the six bobs together in a labelled tray or box so the set stays complete and organised.

LabEquip supplies mechanics apparatus and general lab equipment for schools and colleges. This pendulum bob set pairs well with our Round Stop Clock for timing oscillations accurately, and our full range of lab equipment covers the rest of the mechanics syllabus.

FAQ

Q: Does a heavier bob make the pendulum swing faster?
A: For an idealised simple pendulum, the period depends mainly on the length of the string and gravity, not on the bob’s mass — this set lets students verify that experimentally by comparing different metal bobs.

Q: What metals are included in the set?
A: The exact metals, masses and dimensions of the six bobs are not specified for this listing. Please contact our sales team to confirm before you order.

Q: Do I need a separate stand and thread to use this set?
A: Yes, the bobs are designed to be used with a compatible suspension thread and pendulum support, which should be arranged separately unless confirmed as included.

Q: What experiments is this set commonly used for?
A: It supports experiments on simple pendulum motion, oscillation period, and comparing how different bob masses and materials do or do not affect the period.

Q: How should the bobs be stored between classes?
A: Keep all six bobs together in a labelled tray or box, wiped clean and dry, so the set remains complete and doesn’t tarnish.

Q: What age group typically uses this set?
A: It is commonly used in secondary-school, college and university physics courses wherever simple harmonic motion and pendulum experiments are taught.
