G

G = 6.674 × 10-11 N * m2/kg2

4

gravity vector field

m0 = mass of test particle

Kepler’s Laws

  1. All planets move in ellipses, with the sun at a foci.

  2. dA/dt = constant (r = radius between Sun and planet)

  3. T2 = (4π2/GM)r3 (T2 is proportional to r3)

6

Potential energy between two bodies

7

Energy (circular & elliptical orbits)
