Kepler published the first two laws of planetary motion by analyzing the astronomical observations of Tycho Brahe. The first law states that planets move in elliptical orbits with the sun at one focus. The second states that the radius vector of a planet sweeps out equal areas in equal times. His beliefs were very controversial at that time.
The laws are three fundamental laws of classical physics. The first states that a body continues to move or stay still unless there's an external force. The second states that f=ma. The third states that if one body exerts a force on another, there is an equal and opposite force exerted by the second body on the first.
