The tendency of an object to stay at rest or to remain in motion until acted upon by an outside force is

• inertia
• motion
• friction
• gravity

What is Newton's First Law

• F=ma
• Every action has an equal and opposite reaction
• An object at rest stays at rest, an object in motion stays in motion. 
• Friction 

An object following a straight-line path at a constant speed 

• has zero acceleration
• has no forces acting on it
• has a net force acting in the direction of motion
• none of these
