This law suggests an inferesting idea about motion that was very radical when it was first articulated (actually by Galileo), and remains surprising to most people when they first encounter it. Objects at rest remain at rest, The natural state of motion of an object is to 2 3 & : remain at rest, if it is already at rest, or fo and objects in motion remain remain in motion at constant velocity, if it is in motion with the same already moving. The law is usually stated as velocity, unless acted upon follows: by an unbalanced force
