HS-PS3-5
Develop and use a model of two objects interacting through electric or magnetic fields to illustrate the forces between objects and the changes in energy of the objects due to the interaction.
Clarification statement: Examples of models could include diagrams, texts, algebraic expressions, and drawings representing what happens when two charges of opposite polarity are near each other.
Assessment boundary: Assessment is limited to systems containing two objects.
Note: This is a performance expectation for both HS Physics and HS Chemistry. For chemistry, there is a focus on "atomic structure, interaction of subatomic particles, binding energy, bond formation, polarity, intermolecular forces, non-ideal gas behavior" (as per the NYSED high school course maps).

NGSS Dimensions
Performance expectation HS-PS3-5 was developed using the following elements from the NRC document A Framework for K-12 Science Education:
- Developing and Using Models
- Develop and use a model based on evidence to illustrate the relationships between systems or between components of a system.
- PS3.C: Relationship Between Energy and Forces
- When two objects interacting through a field change relative position, the energy stored in the field is changed.
- Cause and Effect
- Cause and effect relationships can be suggested and predicted for complex natural and human designed systems by examining what is known about smaller scale mechanisms within the system.
