How It Is Used
Because the bobs share one volume, weighing them shows directly how density differs between metals. Hung in turn on the same thread, they show that a simple pendulum’s period does not depend on the mass of the bob, and they can be heated for specific heat comparisons by the method of mixtures.
Frequently Asked Questions
Which metals are in the Bob Set Of 6 Metals?
Brass, copper, aluminium, iron (steel), lead and zinc, one 25 mm sphere of each.
Why are the bobs in the Bob Set Of 6 Metals all the same size?
Equal 25 mm diameters give equal volumes, so differences in mass come only from density, and pendulum tests compare mass alone.
