problem on newtons first and second law

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

• Friction
• Mass
• Inertia
• 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. unless a resultant force acts on it

• Friction

Which has more Inertia? (so need more force to move) 

• Truck
• Ant
• A cat
• A skateboard
