the kinetic store is at a maximum and the gravitational store is at a maximum
the kinetic store is at a minimum and the gravitational store is at a maximum
the kinetic store is at a maximum and the gravitational store is at a minimum
the kinetic store is at a minimum and the gravitational store is at a minimum
