The student will: **Learning Objective (2.B.2.1):** The student is able to apply

*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*.

**Learning Objective (2.B.2.2):**The student is able to 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.

**Learning Objective (3.A.2.1):** The student is able to represent forces in diagrams or mathematically using appropriately labeled vectors with magnitude, direction, and units during the analysis of a situation.

**Learning Objective (3.A.3.1):** The student is able to 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.

**Learning Objective (3.A.3.2):** The student is able to challenge a claim that an object can exert a force on itself.

**Learning Objective (3.A.3.3):** The student is able to describe a force as an interaction between two objects and identify both objects for any force.

**Learning Objective (3.A.4.1):** The student is able to construct explanations of physical situations involving the interaction of bodies using Newton’s third law and the representation of action-reaction pairs of forces.

**Learning Objective (3.A.4.2):** The student is able to use Newton’s third law to make claims and predictions about the action-reaction pairs of forces when two objects interact.

**Learning Objective (3.A.4.3):** The student is able to analyze situations involving interactions among several objects by using free-body diagrams that include the application of Newton’s third law to identify forces.

**Learning Objective (3.B.1.1):** The student is able to predict the motion of an object subject to forces exerted by several objects using an application of Newton’s second law in a variety of physical situations with acceleration in one dimension.

**Learning Objective (3.B.1.2):** The student is able to 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.

**Learning Objective (3.B.1.3):** The student is able to re-express a free-body diagram representation into a mathematical representation and solve the mathematical representation for the acceleration of the object.

**Learning Objective (3.B.2.1):** The student is able to create and use free-body diagrams to analyze physical situations to solve problems with motion qualitatively and quantitatively.

**Learning Objective (3.C.1.1):** The student is able to use Newton’s law of gravitation to calculate the gravitational force the two objects exert on each other and use that force in contexts other than orbital motion.
