PS2 Motion and Stability: Forces and Interactions

PS2.A Forces and Motion
- 9-12.PS2.A.1 Analyze data to support and verify the concepts expressed by Newton's 2nd law of motion, as it describes the mathematical relationship among the net force on a macroscopic object, its mass, and its acceleration.
- 9-12.PS2.A.2 Use mathematical representations to support and verify the concepts that the total momentum of a system of objects is conserved when there is no net force on the system.
  - Conservation of momentum (Ph-G.1)
- 9-12.PS2.A.3 Apply scientific principles of motion and momentum to design, evaluate, and refine a device that minimizes the force on a macroscopic object during a collision.
PS2.B Types of Interaction
- 9-12.PS2.B.1 Use mathematical representations of Newton's Law of Gravitation to describe and predict the gravitational forces between objects.
- 9-12.PS2.B.2 Plan and conduct an investigation to provide evidence that an electric current can produce a magnetic field and that a changing magnetic field can produce an electric current.
  - Magnets and magnetism (Ph-R.1)
  - Magnetic field calculations: solenoids (Ph-R.3)

PS3 Energy

PS3.A Definitions of Energy
- 9-12.PS3.A.1 Create a computational model to calculate the change in the energy of one component in a system when the changes in energy are known.
  - Conservation of mechanical energy (Ph-H.2)
  - The first law of thermodynamics (Ph-J.2)
- 9-12.PS3.A.2 Develop and use models to illustrate that energy at the macroscopic scale can be accounted for as a combination of energy associated with the motions of particles (objects) and energy associated with the relative position of particles (objects).
  - Conservation of mechanical energy (Ph-H.2)
- 9-12.PS3.A.3 Design, build, and refine a device that works within given constraints to convert one form of energy into another form of energy.
PS3.B Conservation of Energy and Energy Transfer
- 9-12.PS3.B.1 Plan and conduct an investigation to provide evidence that the transfer of thermal energy when two components of different temperature are combined within a closed system results in a more uniform energy distribution among the components in the system (second law of thermodynamics).
PS3.C Relationship Between Energy and Forces
- 9-12.PS3.C.1 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.

PS4 Waves and Their Applications in Technologies for Information Transfer

PS4.A Wave Properties
- 9-12.PS4.A.1 Use mathematical representations to support a claim regarding relationships among the frequency, wavelength, and speed of waves traveling in various media.
- 9-12.PS4.A.2 Evaluate the claims, evidence, and reasoning behind the idea that electromagnetic radiation can be described either by a wave model or a particle model, and that for some situations one model is more useful than the other.
PS4.B Electromagnetic Radiation
- 9-12.PS4.B.1 Communicate technical information about how electromagnetic radiation interacts with matter.
- 9-12.PS4.B.2 Evaluate the validity and reliability of claims in published materials of the effects that different frequencies of electromagnetic radiation have when absorbed by matter.
