Clarification Statement - S.MS.PS.3.2.CS:
Emphasis is on relative amounts of potential energy, not on calculations of potential energy. Examples of objects within systems interacting at varying distances could include: the Earth and either a roller coaster cart at varying positions on a hill or

Assessment Boundary - S.MS.PS.3.2.AB:
Assessment is limited to two objects and electric, magnetic, and gravitational interactions.

Science and Engineering Practices - 6-8.SEP2.2:
Develop a model to describe unobservable mechanisms.

Disciplinary Core Ideas - S.MS.PS.3.2.DCI:
PS3.A: Definitions of Energy •A system of objects may also contain stored (potential) energy, depending on their relative positions. PS3.C: Relationship Between Energy and Forces •When two objects interact, each one exerts a force on the other that can cause energy to be transferred to or from the object.

Crosscutting Concepts - CC3.3:
Models can be used to represent systems and their interactions—such as inputs, processes and outputs—and energy and matter flows within systems.
