Johannes Kepler Used Tycho’s data to confirm Copernicus’ theory that the sun was the center of the universe Kepler’s 3 Laws of Motion First Law: All orbits are not circular but elliptical Kepler’s findings destroyed Aristotelian Physics

Newton’s Laws First Law: Every object continues in a state of rest or uniform motion in a straight line until deflected by a force Second Law: The rate of change of motion on an object is proportional to the force acting on it (Force = mass x acceleration) Third Law: For every action there is an equal and opposite reaction Law of Gravitation: every object in the universe is affected by gravity
