Newton's Three Laws of Motion Quiz

According to Newtons first law of motion, an object at rest will remain at rest unless acted on by an unbalanced force. An object in motion continues in motion with the same speed and in the same direction unless acted upon by an unbalanced force. What is this law often called?

• law of force

• law of rest

• law of balance

• law of inertia

What does the first law of motion mean?

• there is a natural tendency of objects to keep on doing what they're doing.

• all objects will change no matter what they're doing

• force causes objects to resist change in motion

In the absence of a (an)________________ force, an object in motion will maintain this state of motion.

• balanced

• unbalanced
