An object at rest will remain at rest unless an external force is applied.
An object in motion will remain in motion with a constant velocity regardless of external forces.
An object in motion will eventually come to rest if no force is applied.
An object at rest will remain at rest and an object in motion will remain in motion with a constant velocity unless acted on by a net external force. (correct)

The SI unit of mass is the kilogram (kg).
The gravitational force acts through empty space.
Newton's First Law states that an object at rest will remain at rest, and an object in motion will continue to move with a constant velocity, unless acted upon by an external force.
The property of an object that specifies how much resistance it exhibits to changes in its velocity is called inertia.
The weight of an object is equal to the magnitude of the gravitational force exerted on it.
