Newton's First Law is also known as The Law of

• Friction

• Mass

• Inertia

• Gravity

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 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 

Which one needs a greater net force to move, a kilogram of feathers or a kilogram of iron? 

• feathers 
• iron
• same
• depends on their friction
