According to Newton’s First Law of Motion, what will happen to a moving object if there is no unbalanced force acting on it?

• It will continue in motion.

• It will eventually come to a stop.

• It will transfer energy to another object.

• It will accelerate in the absence of friction.

According to Newton’s First Law of Motion, what will happen to an object if there is no force acting on it?

• at rest, it would remain at rest

• in motion, it would remain in motion

• both A and B

• neither A nor B
