During the practical last lesson, we investigated three factors which may have an effect upon the period of a simple pendulum:
Consider a simple pendulum with a bob of mass m suspended by a thread of length L.
Which has a displacement s from the equilibrium position giving an angle to the vertical
This work was first carried out in 1581 by Galileo when he observed lamps swinging backwards and forwards in the cathedral at Pisa
Since clocks had not yet been invented he used his own pulse for timing!
Having conducted the experiment how could it be improved?Why are the pendulum bobs in clocks not spherical?
