Physicists study the science of a moving baseball using natural laws that have been known for hundreds of years. These laws aren’t regulations enforced by the science police. Instead, natural laws are descriptions of the way nature behaves, both invariably and predictably. In the 17th century, physics pioneer Isaac Newton first put into writing a famous law that describes an object in motion.
Newton’s First Law states that a moving object will keep moving in the same direction unless some outside force acts upon it. It also says that an object at rest won’t move without the prodding of some outside force. That means a baseball will stay put unless a force — like a pitch — propels it. And once a baseball is moving, it will keep moving at the
