Specific Expectations
D1.1 analyse the operation of a technological system that uses gravitational, electric, or magnetic fields (e.g., a home entertainment system, a computer, magnetic strips on credit cards) [AI, C]
D1.2 assess the impact on society and the environment of technologies that use gravitational, electric, or magnetic fields (e.g., satellites used in surveillance or storm tracking, particle accelerators that provide high-energy particles for medical imaging) [AI, C] D2.1 use appropriate terminology related to fields, including, but not limited to: forces, potential energies, potential, and exchange particles [C] D2.2 analyse, and solve problems relating to, Newton’s law of universal gravitation and circular motion (e.g., with respect to satellite orbits, black holes, dark matter) [AI] D2.3 analyse, and solve problems involving, electric force, field strength, potential energy, and potential as they apply to uniform and non-uniform electric fields (e.g., the fields produced by a parallel plate and by point charges) [AI] D2.4 analyse, and solve problems involving, the force on charges moving in a uniform magnetic field (e.g., the force on a current-carrying conductor or a free electron) [AI] D2.5 conduct a laboratory inquiry or computer simulation to examine the behaviour of a particle in a field (e.g., test Coulomb’s law; replicate Millikan’s experiment or Rutherford’s scattering experiment; use a bubble or cloud chamber) [PR] |
D3.1 identify, and compare the properties of, fundamental
forces that are associated with different theories and models of physics (e.g., the theory of general relativity and the standard model of particle physics) D3.2 compare and contrast the corresponding properties of gravitational, electric, and magnetic fields (e.g., the strength of each field; the relationship between charge in electric fields and mass in gravitational fields) D3.3 use field diagrams to explain differences in the sources and directions of fields, including, but not limited to, differences between near- Earth and distant fields, parallel plates and point charges, straight line conductors and solenoids |
