Step 1 : Introduction to the question "Who is famous for having discovered the three laws of motion?"
...Sir Isaac Newton was a physicist and mathematician who developed the principles of modern physics, including the three laws of motion, and is credited as one of the great minds of the 17th century Scientific Revolution. Sir Isaac Newton introduced the three laws of motion in 1687 in his book entitled Philosophiae Naturalis Principia Mathematica, which has been called the most influential book on physics. Newton's three laws of motion describe the relationship between a body and the forces acting upon it, and its motion in response to those forces.
