According to Newton's First Law of Motion, what will happen to an object at rest if no unbalanced force acts on it?

• It will start moving.

• It will remain at rest.

• It will accelerate.

• It will change direction.

According to Newton's First Law, what will happen to an object moving in a straight line at a constant speed if no external force acts on it?

• It will stop.

• It will change direction.

• It will continue moving in a straight line at a constant speed.

• It will accelerate.

A distance-time graph shows a straight line with a positive slope. What does this indicate about the object's motion?

• The object is at rest.

• The object is moving at a constant speed.

• The object is accelerating.

• The object is decelerating.
