HS-PS2-2: Conservation of Momentum
Use mathematical representations to support the claim that the total momentum of a system of objects is conserved when there is no net force on the system. (Systems and System Models)
Clarification Statement: Emphasis is on the quantitative conservation of momentum in interactions and the qualitative meaning of this principle.
Assessment Boundary: Assessment is limited to systems of two macroscopic bodies moving in one dimension.

ELA/Literacy
WHST.11-12.7 - Conduct short as well as more sustained research projects to answer a question (including a self-generated question) or solve a problem; narrow or broaden the inquiry when appropriate; synthesize multiple sources on the subject, demonstrating understanding of the subject under investigation.
Mathematics
HSA-CED.A.1 - Create equations and inequalities in one variable and use them to solve problems. Include equations arising from linear and quadratic functions, and simple rational and exponential functions.
HSA-CED.A.2 - Create equations in two or more variables to represent relationships between quantities; graph equations on coordinate axes with labels and scales.
HSA-CED.A.4 - Rearrange formulas to highlight a quantity of interest, using the same reasoning as in solving equations.
HSN-Q.A.1 - Use units as a way to understand problems and to guide the solution of multi-step problems; choose and interpret units consistently in formulas; choose and interpret the scale and the origin in graphs and data displays.
HSN-Q.A.2 - Define appropriate quantities for the purpose of descriptive modeling.
HSN-Q.A.3 - Choose a level of accuracy appropriate to limitations on measurement when reporting quantities.
MP.2 - Reason abstractly and quantitatively.
MP.4 - Model with mathematics.
