What law is best described by inertia?

• 1st

• 2nd

• 3rd

• law of conservation of mass

What Unit do we Measure Force in?

• Newtons

• Joules

• Force

• Kilograms

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 

Why is the net force 0 in the image?

• Because the elephants are the same size
• Because they are both pulling the same amount of force in opposite directions
• Because they are elephants
• Because they are pulling away from each other.
