Newton's Laws of Motion Quiz

What does Newton's first law of motion state?

• An object will not change its motion unless acted upon by a force.

• Heavier objects need a larger force to move them.

• For every action, there is an equal and opposite reaction.

• Objects in motion will eventually stop on their own.
