1. The Simple Pendulum

2. What did we measure? What things affected the period of the pendulum?

4. Is there a real effect here or just an illusion?

8. Is it a straight line or a curve?

10. KE vs PE KE should equal PE PE at ends of pendulum swing should equal KE at center PE at top of roller coaster run should equal KE at bottom PE at top of building should equal KE at bottom

11. Pendular Motion Where T is the period, L is the length of the pendulum, and g is the acceleration due to gravity. T is a function of length. It has a weak dependence on the angular displacement and should not be affected by the mass. The period of the simple pendulum is given by

12. The Complex Pendulum Chaotic behaviour
