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

• Friction
• Mass
• Inertia

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

• acceleration
• inertia
• mass
• frame of reference

friction is a force that acts...

• in the same direction as the motion
• opposite to the direction of the motion
• opposite to the applied forces
• the same direction as the applied force

What can a force do?

• start a motion
• stop a motion
• all of the above
• change the direction of the motion
