I want to know the answer to the following question:
What concept did the Law of Gravitation deal with?
All the background I'm provided with is that "In 1687, Isaac Newton published the Principia Mathematica, detailing two comprehensive and successful physical theories: Newton's laws of motion, which led to classical mechanics; and Newton's Law of Gravitation, which describes the fundamental force of gravity.". Is that enough to answer the question?
Answer: yes
