Newton's 3 Laws of Motion

What is Newton's First Law of Motion?

• F=m x a
• Every action has an equal and opposite reaction
• An object at rest stays at rest, an object in motion stays in motion unless acted on by another force. 
• Friction 

What is Newton's First Law known as? The Law of

• Friction
• Mass
• Inertia
• Gravity

What is inertia?

• the force that opposes motion
• the force of attraction between 2 objects
• an object's tendency to stay in motion or to stay at rest
• a change in an object's speed and/or direction
