Newton's Laws of Motion

Newton's Law of Inertia describes the motion of-

• Objects at rest only
• Objects in motion only
• Objects at rest and objects that are in motion
• Objects without a mass and resist being set into motion

Which law best explains how objects accelerate when a force is applied?

• Newton's Law of Inertia
• Newton's Law of F=ma
• Newton's Law of Force Pairs
• Newton's Law of Chemistry

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
