If lil Houdeshell weighs 378 Newtons on Earth and 63 Newtons on the moon, this means that her...

• mass is greater on earth.
• mass is greater on the moon.
• inertia is greater on earth and less on the moon.
• mass is the same on the moon and the earth.

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

Which best explains why we are able to accelerate forward when starting to run?

• As one leg moves backward, it provides an equal and opposite force for the other foot to move forward.
• No acceleration takes place. Runners are always at a fixed velocity.
• The striking foot pushes backward against the ground. The friction with the ground provides an equal and opposite force forward.
• The runner's upper body quickly leans forward, causing the entire body to begin accelerating forward
