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 

After a cannonball is fired into frictionless space, the amount of force needed to keep it going equals

• twice the force with which it was fired
• the same amount of force with which it was fired
• 1/2 the force with which it was fired
• zero, since no force is requires to keep it moving.

• Objects react to outside forces
• Unbalanced forces on an object keep it at rest
• More mass = more inertia
