Newton’ laws of Motion

  1. An object continues at rest or in uniform motion in a straight line unless acted upon by some force.
  2. An object’s change of motion is proportional to the force acting on it and is in the direction of the force.
  3. When one body exerts a force on a second body, the second body exerts an equal and opposite force back on the first body (action and reaction). Kepler’s Laws of Planetary Motion
  4. Planets travel on elliptical orbits with sun at its one of the foci.
  5. Planetary orbits sweep out equal areas in equal time.
  6. The square of the period of any planet is proportional to the cube of the semimajor axis of its orbit. P^2 Year=a^3 AU
