Chapter 7 Motion
... • A powerful locomotive begins to pull a long line of boxcars that were sitting at rest. Since the boxcars are so massive, they have a great deal of inertia and it takes a large force to change their motion. Once they are moving, it takes a large force to stop them. • On your way to school, a bug fl ...

... This law states: "An object will remain at rest unless acted on by an external and unbalanced force. An object in motion will remain in motion unless acted on by an external and unbalanced force." This means that an object that isn't moving won't move unless a force makes it move. It also says that ...
