This is a Foucault Pendulum.   It moves back and forth, but over the course of 24 hours, it will knock down all the pegs in the circle because of the earth's movement.

How would you create an energy diagram(s) for this over the course of one swing?  Over the course of 24 hours?   Do this individually, and explain your reasoning.

Do the same with this.


Assessment:  Springs and Pendulums

You will create your own Newton's Cradle.   In this case, the balls act as a type of spring, so imagine how you could use the concept of Hooke's Law to calculate a spring constant for the system.  Also, calculate the period of the pendulum of one ball.
