Newton's 1st and 2nd law review

What is Newtons 1st law of motion?

• Force= Mass multiplied by acceleration 
• An object at rest stays at rest unless acted on an unbalanced force. (inertia)
• For every action there is a equal and opposite  re-action.
• law of gravity 

What is Newtons 2nd law of motion?

• Pancakes 
• Force= Mass multiplied by acceleration
• For every action there is a equal and opposite  re-action.
• Law of gravity 

What law of motion does this picture represent?

• Newtons 1st law
• law of gravity 
• Newtons 4th law
