Law of Universal Gravitation:

Newton's Gravitation Equation G = 6.67 10-11 N-m2/kg2

Developers of Gravitational Theory:

Gravity Field of a Uniform Sphere:

Kepler's Laws:

  1. Elliptical motion
  2. Equal areas in equal times
  3. Square-of-period over cube-of-average-radius of orbit is constant: T2/r3 = constant
