2.2 The student can apply mathematical routines to quantities that describe natural phenomena.
7.2 The student can connect concepts in and across domain(s) to generalize or extrapolate in and/or across enduring understandings and/or big ideas.*
3.C.1.1 Use Newton’s law of gravitation to calculate the gravitational force that two objects exert on each other and use that force in contexts other than orbital motion. [SP 2.2]
3.C.1.2 Use Newton’s law of gravitation to calculate the gravitational force between two objects and use that force in contexts involving orbital motion (for circular orbital motion only in Physics 1). [SP 2.2]
Gravitational force describes the interaction of one object with mass with another object with mass.
The gravitational force is always attractive.
The magnitude of force between two spherically symmetric objects of mass m1 and m2 is
where r is the center-to-center distance between the objects.
c. In a narrow range of heights above Earth’s surface, the local gravitational field, g, is approximately constant.
