Using the information learned from the pendulum demonstration, when the pendulum is at it's lowest point, what type of energy does it have and WHY?

Explanation:

the simple pendulum system undergoes a simple harmonic motion in which at the equilibrium position,it kinetic energy is maximum making the potential energy to be zero but when the pendulum is at it extreme position,the P.E becomes max while the K.E becomes min.At the equilibrium position velocity is very high

gravity causes stares to cluster i think so

the number of valence electrons for each molecule or ion is shown beneath the structure. remember hydrogen will not have more than two electrons. this hydrogen is part of a covalent bond (sharing two electrons). a double bond here would cause hydrogen to share four electrons with phosphorus.
