About This Product

Bobs of the same size in different metals let students show that the period of a simple pendulum depends on its length, not on the mass of the bob, and then use the period to work out the acceleration due to gravity. Different diameters help when studying air resistance and finding the centre of the bob for length measurements. Schools, colleges and institutes in Mexico, Mauritius, Yemen, Belize and Sri Lanka can order the Pendulum Bobs or Spheres from Educational Instrument.
