Learning Targets

  • Model verbally or visually the properties of a system based on its substructure and relate this to changes in the system properties over time as external variables are changed. [LO 1.A.5.1, SP 1.1, SP 7.1]
  • Describe a force as an interaction between two objects and identify both objects for any force. [LO 3.A.3.3, SP 1.4]
  • Analyze a scenario and make claims (develop arguments, justify assertions) about the forces exerted on an object by other objects for different types of forces or components of forces. [LO 3.A.3.1, SP 6.4, SP 7.2]
  • Represent forces in diagrams or mathematically using appropriately labeled vectors with magnitude, direction, and units during the analysis of a situation. [LO 3.A.2.1, SP 1.1]
  • Design a plan to collect and analyze data for motion (static, constant, or accelerating) from force measurements and carry out an analysis to determine the relationship between the net force and the vector sum of the individual forces. [LO 3.B.1.2, SP 4.2, SP 5.1]
  • Reexpress a free-body diagram representation into a mathematical representation and solve the mathematical representation for the acceleration of the object. [LO 3.B.1.3, SP 1.5, SP 2.2]
  • Create and use free-body diagrams to analyze physical situations to solve problems with motion qualitatively and quantitatively. [LO 3.B.2.1, SP 1.1, SP 1.4, SP 2.2]
  • Articulate situations when the gravitational force is the dominant force and when the electromagnetic, weak, and strong forces can be ignored. [LO 3.G.1.1, SP 7.1]
  • Apply g =G M / r 2 to calculate the gravitational field due to an object with mass M, where the field is a vector directed toward the center of the object of mass M. [LO 2.B.2.1, SP 2.2]
  • Approximate a numerical value of the gravitational field(g) near the surface of an object from its radius and mass relative to those of the Earth or other reference objects. [LO 2.B.2.2, SP 2.2]
  • Use Newton’s law of gravitation to calculate the gravitational force between two objects and use that force in contexts involving circular orbital motion. [LO 3.C.1.2, SP 2.2
