HS-PS2-4
From NY Science Standards Wiki
Use mathematical representations of Newton’s Law of Gravitation and Coulomb’s Law to describe and predict the gravitational and electrostatic forces between objects.
Clarification statement: Emphasis is on both quantitative and conceptual descriptions of gravitational and electric fields.
Assessment boundary: Assessment is limited to systems with two objects.

NGSS Dimensions
Performance expectation HS-PS2-4 was developed using the following elements from the NRC document A Framework for K-12 Science Education:
Science and Engineering Practices
- Using Mathematics and Computational Thinking
- Use mathematical representations of phenomena to describe explanations.
Disciplinary Core Ideas
- PS2.B: Types of Interactions
- Newton's law of universal gravitation and Coulomb's law provide the mathematical models to describe and predict the effects of gravitational and electrostatic forces between distant objects.
- Forces at a distance are explained by fields (gravitational, electric, magnetic) permeating space that can transfer energy through space. Magnets or electric currents cause magnetic fields; electric charges or changing magnetic fields cause electric fields.
Crosscutting Concepts
- Patterns
- Different patterns may be observed at each of the scales at which a system is studied and can provide evidence for causality in explanations of phenomena.
