Newton's Laws of Motion Review

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

• feathers 
• iron
• same
• depends on their friction
