Quick Answer: The Simple Pendulums Apparatus is a pendulum stand for studying oscillation and simple harmonic motion with bobs hung on strings from a fixed support. Changing the string length shows how length sets the time period.

Key Features
Support stand with suspension point for pendulum bobs on strings
Pendulum length measured from suspension point to the centre of the bob
Bobs swing about a mean position when displaced and released
Used for time period, frequency, amplitude and gravity experiments
About This Product
Students release a bob from a small displacement, time a set number of oscillations and divide to find the period, then change the length and repeat. The results show that the period depends mainly on length, and they lead into the restoring force, energy changes during a swing and a value for the acceleration due to gravity.
Frequently Asked Questions
How is the time period found?
Record the time for a fixed number of oscillations with a stopwatch or digital timer and divide it by the number of oscillations.
