About This Product
Timing swings for different cord lengths lets students plot period against length and calculate the acceleration due to gravity. Changing to a bob of a different metal with the length unchanged shows that, for small swings, mass does not alter the period. The effective length is measured from the split-cork block to the centre of the bob, so the bob’s radius is added to the string length. Enquiries from Lebanon, Mali, Central African Republic, Latvia and Montenegro for the Simple Pendulum Apparatus STEM Lab receive an export quotation.
Frequently Asked Questions
How is the effective length of the Simple Pendulum measured?
From the lower edge of the split-cork block to the centre of the bob, which means adding the bob’s radius to the measured string length.
Does the bob material change the period?
No. For small swings the period depends on length, not on the mass of the bob, which the three different bobs let students check.
