The Foucault Pendulum is named for the French physicist Jean Foucault (pronounced Foo-koh), who first
Add more weight to a pendulum to counteract friction and make the swinging last longer. Ive found that 5 lb (2 x 2) on the rotary pendulum, and 7 lb (3 x 2) on the other two works fairly well. Note that adding more weight does not generally change the frequency of the pendulum. Phase and Amplitude
