Newton`s Three Laws
... Newton’s First Law of Motion • An object at rest remains at rest unless acted on by an unbalanced force. • An object in motion continues in motion with the same speed and direction unless acted upon by an unbalanced force. • This law is often called “the law of inertia". ...
