Chapter 6 - Momentum

6.5 - Conservation of Momentum

• HS-PS2-2. 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.
  • 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.

6.6 - Collisions

• HS-PS2-2. 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.
• HS-PS2-3. Apply scientific and engineering ideas to design, evaluate, and refine a device that minimizes the force on a macroscopic object during a collision.*
  • Clarification Statement: Examples of evaluation and refinement could include determining the success of the device at protecting an object from damage and modifying the design to improve it. Examples of a device could include a football helmet or a parachute.
  • Assessment Boundary: Assessment is limited to qualitative evaluations and/or algebraic manipulations.

6.7 - More Complicated Collisions

• HS-PS2-2. 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.
