Sir Isaac Newton was the first to develop the three laws of motion.
Isaac newton discovered the three principles of planetary motion
According to Kepler's laws of planetary motion, planetary orbits are in the shape of an ellipse with the Sun at one of the foci.
Johann Kepler
Johannes Kepler in the early 17th century. He developed his three laws of planetary motion, with the first law stating that planets move in elliptical orbits with the Sun at one focus.
Johannes Kepler
Johannes Kepler, a German astronomer and mathematician, developed the three laws of planetary motion known as Kepler's laws. He used data collected by Danish astronomer Tycho Brahe to accurately describe the paths of celestial bodies.
I am not sure how much detail you want. But basically he explained Newton's three Laws of Motion, Newton's Law of Gravitation and developed Kelper's Laws of Planetary Motion.
No. Kepler discovered the laws using Tycho Brahe's data.
Johannes KeplerHis first two laws were published in Astronomia Nova(The New Astronomy) in 1609. His Third Law was published in 1618, in book five of his Harmonices Mundi (The Harmonies of the World.)
