The FIRST part of Newton's 1st law states:
An object at rest will stay at rest
An object in motion will stay in motion
An object at rest will stay in motion
An object in motion will stay at rest
The SECOND part of Newton's 1st law states:
An object at rest will stay at rest
An object in motion will stay in motion
An object at rest will stay in motion
An object in motion will stay at rest
The THIRD part of Newton's 1st law states things will move the way they are moving right now...:
