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.

According to Newton’s first law of motion, a moving object that is not acted on by an unbalanced force will

• remain in motion.
• eventually come to a stop.
• change its momentum.
• accelerate.

Acceleration is caused by a force acting on a mass.

• Newton’s first law of motion
• Newton’s second law of motion
• Newton’s third law of motion
