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 

What Unit do we Measure Force in? 

• Newtons
• Joules
• grams
• pounds

How can Newton's second law be represented  mathematically? 

• F=MA
• M= F/A
• A= F/M
• All are correct
