The period of oscillation T of a small spherical mass supported by a length l of thread is given by the expression:

T = 2π√I/g

Where g is the acceleration due to gravity. Design a laboratory experiment using this expression to determine the acceleration due to gravity. You should draw a diagram showing the arrangement of your equipment. In your account, you should pay particular attention to:
. The procedure to be followed
. The measurements to be taken
. Analysis of the data to determine g
. Any safety precautions that you would take.
