Mechanical Energy and the Pendulum
... In this lab we shall investigate the extent to which equation 1 holds for two different simple pendulums The first--the focus of Part I-- will be a real 40 gram wood sphere of radius around 4.0 cm suspended by a string equal to one meter in length. The second--in Part II--will be a computer simulate ...
