Force and Translational Dynamics

Net Force and Translational Equilibrium

Newton’s First Law

Unless an external force acts on an object, an object in motion stays in motion and an object at rest stays at rest.

To confirm, observers would need an inertial reference frame (a reference frame still or moving at a constant rate), acceleration would make it look like there are forces that aren't there.
