C1: G, Newton's gravitational constant,
    & his three laws of motion & his universal law of gravity
    * Newton's three laws of motion; for equations, see p. 134 - 135 of TB1.
    * Newton's universal law of gravity: The gravitational force between two massive objects is proportional to the product of the two (rest) masses, and is inversely proportional to the distance between them. The proportional constant is G. For the equation, see p. 138 of TB1.
        ** Units of G;
    * Angular momentum is conserved
        ** Equation for angular momentum; see solution to problem 5 of Quiz 3; solutions to HW4, SA4.1.
    * Energy in Newtonian mechanics is composed of kinetic energy (one for each dimension of the space) and potential energy (due to the gravitational force in the direction of the pull only)
            ** Equations for  kineticenergies, one for each dimension of the space:
                    *** kinetic energy in the radial direction;
                    *** kinetic energy in the angular direction (See HW4, SA4.1, 4.2, & 4.3)
                    *** kinetic energy in the 3rd direction (the direction perpendicular to the above two) = 0.
            ** Gravitation potential energy (usually negative)
                    *** Exact equation, see solution to HW4, SA4.3;
                    *** Exact equation for the difference of two potential energies, HW8, SA8.3.
                    *** Approximate equation Exact equation for the difference of two potential energies at different heights (radii) = MgH.
    * Escape velocity is the velocity at which the sum of the kinetic energy (positive) and the gravitational potential energy (negative) is zero, see HW4,  SA4.3.
