Newton`s Laws of Motion
... Sir Isaac Newton lived during the 1600s. Like all scientists, he made observations about the world around him. Some of his observations were about motion. His observations have been supported by more data over time, and we now call these Newton’s Laws of Motion. His laws explain rest, constant motio ...
