Group: Kat & Chloe

Description of Pendulum: Pendulum made of rope string and bob is a US penny. It is suspended at a constant of 90º and we are changing the length of the string.

Data and Results Table: The Behavior of a Pendulum with the mass of the bob at 2.5g, starting at an 90º angle as the pendulum's length is Varied
