The uniform circular motion of the conical pendulum allows the following to be investigated: centripetal force vs radius of orbit, centripetal force vs orbital period and determination of g.The disc moves almost without friction on its ball bearing, while the bob’s angle with the vertical is read on the graduated, balanced disc.The pendulum’s length can be varied using four interchangeable wires with hooks.

This convection chamber is designed for demonstrating convection processes in air.The simple, illustrative experiments help to clearly explain the principles of convection and facilitate discussion of how high and low pressure and winds arise.
