If these boys are pulling with the same amount of force.  What will happen?

• The boy in blue will win.
• They will not move at all.
• The boy in red will win.
• Both will fall down.

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 

If there was no friction, objects in motion would stay in motion forever.

• true

• false

If an object has MORE _______, it will have more gravitational force.

• mass

• distance
